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.
(1) According to different use occasions and specific purposes: Select the type of metal push button switches according to the use occasion, such as open type, protective type, waterproof type, anti-corrosion type, etc.; select the appropriate form according to the use, such as handle rotating type, key type, etc. type, emergency type, lighted type, etc. For example, […]
The basic concept of metal push button switchMetal push button switch is a kind of power supply that uses modern power electronic technology to control the timing ratio of switch tube registration and turn off to maintain a stable output voltage. Metal push button switches are usually composed of pulse width modulation control ICs and MOSFETs. […]
The difference between a touch switch and a button switch“Self-locking” means that the switch can maintain a certain state through the locking mechanism, and “light touch” means the amount of force used to operate the switch.Generally speaking, mechanical switches may be distinguished as follows:Switches are divided into knob type, toggle type and button type in terms […]
