Supply standard size switch 3 * 6 * 5 flat cover round spring key switch Light touch switch Introduction Light touch switch is an electronic switch and belongs to electronic components. Also known as a button switch, it first appeared in Japan [known as a sensitive switch]. When used, the switch function is closed and connected by applying pressure to the direction of switch operation in order to meet the conditions of operating force. When the pressure is released, the switch is immediately opened, and its internal structure is achieved by changing the force on the metal spring. The light touch switch consists of: insert, base, spring piece, button and cover plate. The waterproof light touch switch adds a layer of polyimide film on the spring piece (as shown in the figure). The light touch switch has the advantages of small contact resistance load, accurate operating force error, and diversified specifications. It has been widely used in electronic equipment and Major appliance, such as audio and video products, digital products, remote controls, communication products, household appliances, security products, games, computer products, fitness equipment, currency verification pens, laser pen keys, etc. Because the light touch switch directly replaces large equipment and high-load buttons with conductive rubber or pot switch hardware shrapnel due to environmental conditions (elastic force less than twice the applied pressure/environmental temperature and humidity conditions, as well as electrical performance), such as medical equipment, television remote controls, etc
