Touch switch is an electronic push switch, which can be switched on by quietly pressing the switch button when it is used. When the switch is released, the switch will be disconnected. Its internal structure depends on the force and elasticity of metal shrapnel to complete the turn-on and turn-off.
Touch switch is widely used in household appliances because of its small size and light weight, such as color TV buttons, DVD machine buttons, computer mouse and so on. But the micro switch also has its shortcomings. Frequent pressing will make the metal fragments tired and lose elasticity and fail. So now most electric buttons are replaced by conductive rubber, such as computer keyboard, remote control and so on.
The touch button switch can also be used to control small power household appliances such as lighting and exhaust fans. The electronic switch is actively disconnected after the power failure in the city, and will not be self-connected when the call comes again (only by pressing the operation button), which can prevent the consumption of electricity or accidents caused by the long-term power-on of electrical appliances.
