Button switching power supplies are widely used in many fields such as household appliances due to their small size, long life, and light touch. A key switch is an electronic switch composed of a socket, a base, a shrapnel, a button and a cover plate. It has the advantages of time delay, widening, external synchronization, anti-interference, high reliability, stable working area, and various specifications.

Button switching power supplies are widely used in many fields such as household appliances due to their small size, long life, and light touch. A key switch is an electronic switch composed of a socket, a base, a shrapnel, a button and a cover plate. It has the advantages of time delay, widening, external synchronization, anti-interference, high reliability, stable working area, and various specifications. It has been widely used in electronic equipment and white goods. There are two types of key switches: self-locking and unlocking. Let's take a look at the direct differences between the two. A self-locking switch generally refers to a switch with a mechanical locking function. After pressing and releasing the button, it will not jump up completely. In the locked state, you need to press it again to unlock it and jump up completely. This type of switch was used in early TVs and monitors to power down directly and completely. The unlock switch means that the button bounces back immediately after being pressed by hand, and the locking function needs to be realized through the circuit. For example, the switch above the induction cooker, range hood and display is the unlock switch. The unlocking button switch can also be understood as the automatic re-entry button, which will be opened as soon as it is released; similarly, the self-locking button switch, that is, if you press it once, will always open until you press it again, and its lock will pop open. , just like your crude pen. The only difference between the light self-locking switch and the ordinary self-locking switch is that the light switch makes full use of the space in the key, and installs a small indicator light bulb or LED, the terminal of which is connected to the zero line, and the other end is generally connected to the switch through a step-down resistor. The normally open contacts are connected in parallel, the only difference between the lamp self-locking switch and the ordinary self-locking switch is that the light switch makes full use of the space in the key to install a small indicator light or LED, its terminal is connected to the neutral line, and the other end is generally It is connected in parallel with the normally open contact of the switch through a step-down resistor. The device also powers the indicator lights when the switch is closed.
Does the external environment affect the service life of the key switch? In fact, the service life of the key switch has a great impact on the environment of the key switch. In different environments, the resistance faced by the key switch during use is also different, so the use environment sometimes determines the service life of the key switch. For example, the operating environment of the key switch is relatively humid, so it is very possible that the moisture outside the key switch may enter the inside of the key switch, causing interference to some internal components. This effect may lead to the use of the key switch. If it needs to be used normally in the later stage, either the broken parts or the key switch should be replaced.
Therefore, when the key switch is used in different environments, the life of the key switch is also different! The more complex the environment, the more unfavorable the service life of the key switch. Therefore, in the process of use, we can take a protective measure for the key switch according to the environment of the key switch, which can increase the service life of the key switch.
For key switches, the material and coating of the shrapnel and contacts are the most important. The materials and processes of the shrapnel and contacts should not only consider their electrical properties, but also their service life. In general, in order to reduce the contact resistance between the shrapnel and the contact, brass or phosphor copper is usually used, and the electroplating is silver. If you encounter iron needles, silver plating can isolate SO2 gas in the air and keep it away from corrosive elements, but the anticorrosion time is short. It would be better to use brass or phosphor bronze pins. Therefore, the material, thickness and processing of the silver-plated layer become the keys to determine the comprehensive performance of the pin.

Key Switch Usage Notes
1. When checking the touch switch during routine maintenance, we should pay attention to whether the key switch has become fragile, deteriorated, decreased in flexibility, or cracked due to time aging. . Many materials of the key switch themselves have the effect of dustproof and electricity isolation, and attention should be paid to maintenance during daily use. People can start from the power isolation material of the key switch to eliminate more hidden dangers of consumption.
2. Due to the high flexibility of the key switch, be careful not to squeeze too hard when pressing. Since the principle is the same whether it is the control button on the fine instrument or the button on the simple one, it is assumed that pressing or tapping with great force will reduce the flexibility of the key switch itself.
3. If you find that the key switch has abnormal operation, remember not to suspend the disassembly without authorization. In the absence of a professional maintenance environment, many high-end electrical products need to be unpacked in a dust-isolated environment. It has the effect of conducting electricity, which is a very risky practice, and it is easy to further damage the switch. Therefore, the inspection and maintenance of the illuminated key switch must be suspended in a special environment.
The purpose of the key switch
To say that the products often used by key switches are the electronics industry, because the TVs, stereos and previous video recorders we often use will use key switches. Computers used in offices, game consoles that can be seen in game halls, fax machines used by companies, walkie-talkies used by security guards, company printers, copiers, machine tool control equipment in workshops, some instruments and our home use some household appliances.
