Working principle of the push button switch
The operating force of the key switch is related to the state of the reed. The starting force is directly proportional to the compression distance of the reed. When the reed is compressed to 5% – 70%, the operating force suddenly decreases, accompanied by a “ticking” sound. There are generally two structures of turtle rubber switch. The operating force curve varies greatly with the geometry of the rubber block.

Usage ofthe push button switch
Key switches are mainly used for color TV sets, black-and-white TV sets, audio equipment, video recorders, video cameras, computers, game consoles, fax machines, walkie talkies, batons, machine tool control devices, copying, printers, electronic instruments, meters and other household appliances.
In the proximity switch, there is a component that has the ability to “perceive” the object approaching it, that is, the displacement sensor. It can use the sensitivity of the displacement sensor to the approaching object to achieve the purpose of controlling the switch on or off. The object moves from the switch to the […]
Sine wave inverter is a kind of inverter, it is the DC electric energy (power battery, battery) into alternating current (generally 220V, 50Hz sine wave) power electronic device. Inverter and ACDC converter are the opposite process. ACDC converter or power adapter will be 220V AC rectifier into direct current to use, and the inverter has […]
Precautions for using button switchesThere is a big difference between the button switch capabilities in AC and DC circuits, and the control capacity is very low in DC applications. This is mainly because DC does not have a zero point like AC, so it is difficult to eliminate the arc once it occurs, and the arc […]
