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.
M24 inductive proximity switch, proximity switch, as the name suggests, when there is an object approaching, the switch automatically on, or off. Automatic control, all kinds of mechanical equipment, machine tools, industrial control, numerical control, production lines and other equipment are inseparable from him. There are several types of proximity switches. Choose according to specific use. […]
(1)(Push button switch)Always check the button to remove dirt. Due to the small contact spacing of the button, after years of use or poor sealing, dust or oil emulsion will flow in, resulting in reduced insulation and even short circuit accidents. In this case, insulation and cleaning treatment must be carried out, and corresponding sealing […]
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 […]
