Classification and Detailed Introduction of Tact Switches
The switches are mainly divided into the following types, Tact Switches, Toggle Switches, Key Switches, direct key switches, power switches, Rocker Switches, etc., Each type is described in detail below. What is a Tact Switch? Tact switch It is an electronic switch, which can be turned on by lightly pressing the switch button when in use. When the hand is released, the switch is turned off. The internal structure of the switch is turned on and off by the force of a metal spring.
The tact switch is composed of: insert, base, shrapnel, button, and cover. The waterproof tact switch adds a layer of polyimide film on the shrapnel. Tactile switches are widely used in home appliances due to their low contact resistance, crisp touch feel, complete height specifications, etc., such as: audio and video products, digital products, remote controls, communications products, household appliances, Security products, toys, computer products, fitness equipment, medical equipment, banknote detectors, laser pen buttons, etc. But the touch switch also has its shortcomings. Frequent pressing will make the metal shrapnel fatigue and lose elasticity and fail.
Therefore, most of the buttons of electrical appliances are now directly replaced by conductive rubber or pot switch hardware springs, such as computer keyboards, TV remote controls, etc. Regarding the pin connection of the five-pin tact switch: two pins are in a group, the four corners are for more stable welding, and the fifth pin is for the ground wire.
