As a manufacturer with many years of production experience, heavy machinery equipment switch selection is very particular.First, let's understand the impact of the site environment on the switch. As we all know, the site environment is very harsh, full of a lot of dust, switches exposed to such an environment for a long time are susceptible to pollution and damage, especially sensitive electrical components are easy to be blocked or breakdown. The site is also constantly exposed to the sun and rain. Long-term sun exposure will cause the switch panel to rot, affecting its appearance and performance, and the erosion of rain will make the switch easy to be damaged by moisture, and even cause short circuit failure. When the site is busy, the switch will experience frequent switching operations in daily use. High frequency use will lead to gradual fatigue and wear of switch components such as springs and keys, increasing the probability of failure. Even heavy machinery and equipment operate in the construction site, the switch panel is also faced with the risk of falling stones. This can cause the panel to crack, damage the internal structure, and pose a safety hazard to the operator. It also faces the risk of stone falling onto the panel, therefore, the quality and stability of the switch must be guaranteed, reduce equipment failure, and improve work efficiency. Therefore, we can understand the importance of choosing a high-quality switch for heavy machinery and equipment. The high quality switch has a sealed design, which can effectively prevent the intrusion of dust and other impurities and extend the service life of the switch. And they have good weather resistance and waterproof performance, can resist the erosion of the sun and rain, to ensure stable and reliable work in harsh environments. In addition, the durable switching materials and structural design can withstand high frequency switching operation, effectively reducing the incidence of failure and ensuring the long-term normal operation of the equipment. In order to protect the safety of the operator, the panel material of the switch needs to be impact-resistant and able to withstand the impact of heavy objects such as stones to prevent breakage and damage. Therefore, in the purchase of switches must choose high quality products. They have undergone rigorous testing and quality control to meet the challenges of the site environment and provide safe and reliable power control for your heavy machinery and equipment.

After the release of the hand, the rocker automatically restores the flatness and feels better and lasts longer.

Introduction Dip switches are mostly used in the program control plate, and the performance circuit of the control components is switched off. Therefore, the dip switch will also be called according to the industry plate: program switch, address switch, and the most familiar dip switch. Application Widely used in data processing, communication, remote control, anti-theft automatic alarm system, air shower, air conditioning control board, train model and other products that need manual programming. Classify Dip switch, as a kind of micro switch that needs manual operation, is widely used in communication, security and many other equipment products. Most DIP switches use in-line (DIP), transform between the two states, and then form different states of 2 to the N power according to different bits to achieve different functions. In fact, there are many kinds of subdivision, the following introduces some specific series. 1:1.27mm half-pitch type Its foot spacing is half of the normal dip switch, that is, Pitch 1.27mm. Main features Small size, less space on the circuit board. Suitable for use in miniature precision equipment. 2:2.54mm flat dial The foot distance is 2.54mm, and the top DIP flat type is adopted, which belongs to two states. The strength of the actuator is up to 800gF in each series, and the shell and actuator are made of PBT, UL94V-0 material. The internal spring sheet is fully gold-plated for high reliability. The operating temperature is -40 to 85 degrees, suitable for industrial grade.

A rotary switch is a switch that operates by rotation. These are often chosen when more than 2 locations are required, such as a three-speed fan or a CB radio with multiple receiving frequencies or "channels". The rotary switch consists of a spindle or "rotor" with a contact arm or "spoke" that protrudes from its surface like a CAM. It has a set of terminals arranged in a circle around the rotor, and each terminal serves as a contact for the "spoke" through which any one of many different circuits can be connected to the rotor. Switch layer, allowing the use of multiple poles; Each layer corresponds to a pole. Alternatively, rotation can be limited to a small part of the circle (half; First third), then each layer can have more than one (two; Three equal poles. Typically, this switch has a pawl mechanism, so it "clicks" from one active position to another, rather than stopping in the middle. As a result, the rotary switch provides a greater pole and throwing capability than a simple switch.

construction The tact switch is divided into two categories: the tact switch using a metal reed as a switch contact piece has a small contact resistance and a cluster of 20mn. Good hand feel, with "ticking" crisp sound. Switching habits that use conductive rubber as a contact path are called conductive rubber switches. The switch feels good, but the contact resistance is large, generally 100 to 300n. The structure of the light touch switch is to move down by the key, so that the contact reed or conductive rubber block contacts the solder and forms a path. summarize The tact switch is composed of: insert, base, shrapnel, button and cover plate. The waterproof tact switch adds a layer of polyimide film on the shrapnel. The tact switch has the advantages of small contact resistance charge, accurate operating force error, diversified specifications, etc. It is widely used in electronic equipment and white goods, such as: video and audio products, digital products, remote controls, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, banknotes, laser pen keys and so on. Because the tact switch on the environmental conditions (pressure is less than 2 times the elastic/ambient temperature and humidity conditions and electrical performance) large equipment and high-load buttons are used conductive rubber or pan switch hardware shrapnel directly to replace, such as medical equipment, TV remote control and so on.

A toggle switch is a manually controlled switch, mainly used for on-off control of AC and DC power circuits, but generally can also be used in circuits of several kilohertz or up to 1 megahertz. It has the characteristics of small size, easy operation, etc., and is a commonly used switch in electronic equipment. Species There are two and three operating positions. The three position switch can have a certain side position is not positioned. At the same time, there are many types of connected circuits. There are many kinds of button handles of button switch, such as metal cone knob, plastic cone knob, fluorescent knob, plastic sleeve knob, spherical knob, flat rod knob, lock rod knob, wave knob, paddle knob and so on. The lock lever type knob is suitable for dangerous operating situations. There is also a "lift unlock" type knob, which is equipped with a spring and a milling groove at the end of the screw tube mouth. The operator must first lift the knob and then push it to another position to ensure safe work. Fold and edit this paragraph model number. Operating Principle In manual operation, the switch action can be divided into two stages. The first stage is to use the hand to pull the lever toward the center until the lever is in a vertical position. At this time, the tip of the single-blade slider gradually moves closer to the middle until the middle position, and the compression spring is further compressed. After the lever is over the vertical position, the single-blade slider moves rapidly in the other direction under the pressure of the compression spring, and drives the lever to turn rapidly, then the moving contact plate is quickly separated from the fixed contact foot on one side and quickly connected with the fixed contact foot on the other side, which is the second stage. At this time, the separation speed of the contact is related to the size of the pressure spring and the friction between the moving parts, and the speed is very high. According to the test, the time from contact disengagement to reconnection is only about milliseconds, and the average speed is a few millimeters of seconds. This speed is many times faster than manual or maneuvering test speed.

Waterproof push button switch, as the name suggests, is a switch that can be operated with wet hands. It can be used safely in humid environments where waterproof button switches are required. There are many brands and types of waterproof button switches on the market, but in a real sense, there are still fewer button switches with good waterproof sealing performance. Among them, the British Arcolectric waterproof button switch has been widely known and recognized by customers for its superior waterproof performance and excellent quality since it was introduced to the market. Waterproof button contact part still can not solve the water isolation. First, IP waterproof standard The main evaluation standard for the waterproof performance of waterproof switches is based on the ip waterproof grade standard. See how waterproof the switch waterproof performance, mainly look at the IPXX two digits XX, the first X is from 0 to 6, the highest grade is 6; The second digit X is from 0 to 8, with the highest grade being 8; Therefore, the waterproof push-button switch has a maximum waterproof rating of IP68. Second, whether the certification is complete ROHS regulations, SGS certification; It also has VDE/DEMKO/KEMA (now using EU ENEC), UL/CSA and other certifications. These are the certification requirements for high quality waterproof push button switches. If it's necessary to export overseas. Third, other criteria for judgment Waterproof button switch design is reasonable, long service life, high temperature resistance, high current impact resistance, to the specific needs of your product, which should be considered.

Micro switch is a small contact interval and fast moving mechanism, with a specified stroke and a specified force for switching action of the contact mechanism, covered by the shell, its external drive rod of a switch, because the switch contact spacing is relatively small, so the name micro switch, also known as sensitive switch. Also known as sensitive switch, quick switch. Pressure actuated fast opening and closing. Used for door switches in anti-theft systems. Operating principle The external mechanical force acts on the action reed through the transmission element (press the pin, button, lever, roller, etc.), and generates an instantaneous action when the action reed is displaced to the critical point, so that the moving contact at the end of the action reed is quickly connected or disconnected from the fixed contact. When the force on the transmission element is removed, the action reed produces reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is completed instantaneously. The microswitch has small contact spacing, short action stroke, small press power and quick on-off. The operating speed of the moving contact has nothing to do with the operating speed of the transmission element.

Daily in the use of switch keys, it should be noted that there can be no water droplets on the surface of the keys, once accidentally let water vapor into the switch, not only affect the sensitivity of the shrapnel, and may cause short circuit leakage, and the human body accidentally contacted, it may cause electric shock and other safety accidents. Therefore, do not touch the micro switch with wet hands to avoid contact with water vapor. Secondly, when using electrical appliances, if the button cap of the tap switch falls off, please pay attention not to touch the exposed metal keys, because people are conductors themselves, touching the metal part of the key of the power switch with their hands, there will be a dangerous accident. And the cap off is generally caused by its fixed instability, if non-technical personnel do not randomly go to repair the switch cap back, which is improper operation, if touch the bare metal shrapnel touch switch, which will cause electric shock accident. The external mechanical force acts on the action reed through the transmission element (press pin, button, lever, roller, etc.). When the action reed is displaced to the critical point, instantaneous action is generated, so that the moving contact at the end of the action reed is quickly connected or disconnected from the stationary contact. There is a Hall switch at the brake handle. When braking, the Hall switch gives a signal voltage to the controller. The motor stops supplying power, the brake handle is released, and the motor recovers normal power supply. There is a normally closed switch at the brake handle. When braking, the microswitch springs up, and the brake signal is closed (low level and high level brake, and low or high voltage is given to the brake signal). The signal is transmitted to the controller, and the MCU gets the brake signal and stops output, that is, stops power supply to the motor. Brake is divided into two modes: simple brake power off and brake back charging (EABS). The former just cuts off the power, while the latter will recover the energy from the inertia of the car through the control of the single chip microcomputer after the power failure, and charge the level (reverse charge), that is, give the motor a reaction force to help the motor slow down as soon as possible. It's called a flexible brake system.

Metal push button switches are generally used in some wet environments, because they can be operated with wet hands, so it is safer. A good drain switch should have excellent water resistance. How does a metal push button switch make it waterproof? Internally, the waterproof metal touch switch is the same as other push button switches. Specially designed metal shrapnel can withstand hundreds of thousands of presses, but also can achieve very excellent key feel; All the difference is the better air tightness of the contacts on the waterproof metal touch switch. In addition to the shrapnel, also added waterproof silicone film, can tightly fill the button switch inside the gap, to ensure the integrity of the overall external structure. Due to the need to ensure sufficient waterproof performance, the production process of waterproof metal touch switch is obviously more complex, need to go through stamping, cleaning, forming and other six processes. In addition, because the waterproof metal touch switch is generally required to meet the waterproof grade above IP67, so there are strict requirements on the processing density of accessories. In some relatively humid environments, it is safer to use metal pushbutton switches. There are many brands and types of waterproof button switches on the market, but in a sense, there are few key switches with good waterproof sealing performance.

Push-button switches are found on all kinds of gadgets, and many baby toys have push-switch symbols. Push-button switches can be seen everywhere in life, everyone is familiar with it, but if it comes to the switch symbol, but we are not so familiar with it. 1. Symbols used to represent models LA, GQ, XB2, LAY3, Y090, AD16... The most common letters indicate the type of pushbutton switch, representing different product categories, there are plastic switches, there are metal buttons, and there are signal indicators. 2. Parameter symbol for the color of the button The colors here include the lamp bead color with the light and the button head color. Common ones are R(red), green (G), white (W), black (N), blue (B), yellow (Y), and orange (O). It should be noted that black is usually distinguished by the letter N and the blue B. 3. Letter symbols used to represent the shape of the head The main head shapes are as follows: the most common round (Y), square (F), rectangle (J), mushroom head (M), spherical (S). Special doorbell type (M) : see product GQ16M-10 for details. 4. Letter symbols that represent the shape of keys This is very common in metal pushbutton switches, common are flat circle (F), high circle (H), convex circle (C), high convex circle (G). This symbol is not usually used. You don't have to memorize it. 5. Symbols for modes of operation This is the most, is also the key symbol to distinguish various button switches, indicators, listed here are some of the most common. Open type operation (K), protection type (H), water discharge type/quick installation type (S), explosion-proof type (B), knob switch (X), key switch (Y), emergency stop switch (TS), self-locking operation (Z), single point with light button (D), ring with light button (E), window with light button (DJ), handle button (XB); Double button (S). You can see that this is the most complicated notation.

There are many types of switches, some of which can be used in many special situations because they contain special properties. For example, waterproof switches can be used in harsh environments. There are many brands producing this kind of switch on the market. When you choose, there are three details that can not be ignored. Waterproofing class Waterproof switch selection of the first thing to pay attention to is the waterproof level. The service life of the switch with different levels of waterproof performance is completely different. According to the IP waterproof level stipulated by the country can be divided into a number of different levels. Generally speaking, the number followed by the IP represents the waterproof level, the first number is from zero to six, the second is from zero to eight. Therefore, the higher waterproof level is IP68. Whether certified or not This type of switch is a special type of switch, when choosing, we should pay attention to understand whether the selected brand or switch has passed the relevant certification. According to the relevant regulations, high-quality switch certification is required, such as the need to pass SGS certification or the EU ENEC certification, through the exclusive certification of switch quality and life are guaranteed. Whether it is suitable The requirements for switches are different in different environments. When choosing this kind of switch, we should pay attention to understand the high temperature resistance and high current impact resistance of the switch, but also pay attention to whether the overall design is reasonable, whether it is suitable for the actual needs. The above three aspects is the choice of waterproof switch needs to pay attention to the three details. Considering these three aspects, the switch selected can ensure its cost performance and quality. In order to avoid any aspect of negligence and affect the service life of the product and the safety of use.

Metal push button switch quality is superior, button with high strength anti - damage function.Not only beautiful and elegant, noble and elegant, the products also have many varieties, multi-standard, multi-purpose and other advantages.To meet the different needs of customers in various industries, it is widely used in various industrial cabinets, household appliances and other industries of key surface control system.The use of the metal switch is not only the light bulbs in the home and other things, especially the computer, mobile phone switch, assuming that these things only useful and unattractive, certainly will not be welcomed by us. Common parts in the home, these devices will also have metal switches, only its area will be much smaller.As people seek to gradually change, now the old things are no longer useful, more and more things are changing, because what we need to do is to ensure that the needs of consumers can be met, so now the metal button switch is now not only to ensure useful also need to ensure beauty.

Push button switch is short for button, usually used to switch on and off the control circuit, it is an electric drive in a low voltage electrical instructions, widely used in a master electrical, in the electrical automatic control circuit, used to manually send control signals to control contactor, relay, electromagnetic starter, etc. Its characteristics are installed in the work of the machine, the instrument, most of the time is in the initial free state of the position, only when there is a requirement to switch to the second state (position) under the action of the external force, when the external force is removed, due to the action of the spring, the switch will return to the initial position. Push-button switch can complete the start, stop, positive and negative rotation, speed change and interlock and other basic control. Usually each pushbutton switch has two pairs of contacts. Each pair of contacts consists of a normally open contact and a normally closed contact. When the button is pressed, the two pairs of contacts act at the same time, the normally closed contact is disconnected, the normally open contact is closed.
