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.
Factors of choosing normally closed contacts for emergency stop buttonsThe emergency stop button contacts on electrical equipment are either normally open contacts or normally closed contacts. Therefore, people often ask whether the emergency stop button uses a normally closed contact or whether it uses a normally open contact. The factors are as follows:1. From the moment […]
Inductive proximity switch sensor is a low cost method for non-contact detection of metal objects. When metal objects move towards or out of the proximity switch, the signal will automatically change, so as to achieve the purpose of detection. Its composition is mainly composed of three parts: amplifier output circuit, switching circuit, oscillator.An oscillator, one of […]
