What is a tactile switch?

       The tact switch is an electronic switch. When used, the switch can be turned on by lightly pressing the switch button. When the hand is released, the switch is turned off. Its internal structure relies on the force of the metal shrapnel to achieve on-off. . Micro switches are widely used in household appliances due to their small size and light weight, such as color TV buttons, DVD player buttons, computer mice, etc. However, the micro switch also has its shortcomings. Frequent pressing will cause the metal shrapnel to fatigue and lose elasticity and fail. Therefore, the buttons of most electrical appliances are now replaced by conductive rubber, such as computer keyboards, remote controls, etc.

It can also be used to control small-power household appliances such as lights and exhaust fans. This electronic switch will automatically disconnect after a power outage and will not turn itself on when another call comes in (you need to press the control button to turn it on), which can avoid power consumption or accidents caused by long-term energization of electrical appliances.

Regarding the connection method of the four corners: the two legs that are far apart can be short-circuited. The four corners are for welding to be more stable.
