A tactile switch is a momentary switch that requires light pressure to activate and lacks self-locking capabilities. When pressed, the contacts are closed, and upon release, they automatically reset and open. The core structure consists of a button cap, a spring plate, a moving/stationary contact, and a housing. It features light activation force, short travel distance, and compact size, and is widely used in signal triggering scenarios for various electronic devices, such as audio-visual products, digital products, remote controls, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, money detectors, laser pointer buttons, and more.
