The tact switch is also called a push button switch. When used to meet the operating force, the pressure switch function is closed and connected to the switch operation direction. When the pressure is withdrawn, the switch will be disconnected. Its internal structure is realized by the force change of metal elastic fragments.

The tact switch consists of: insert, base, shrapnel, button, cover plate. The waterproof tact switch adds a layer of polyimide film on the shrapnel. The tact switch has small contact resistance and accurate operation error. Advantages in terms of diversification of specifications.
