Tact Switch LED Crystal Cap

Tact switch, also known as capacitive switch or touch switch, is an electronic switch that can be operated without pressing a physical button. By sensing the charge or capacitance of the human body, the switch operation can be achieved by simply touching the switch panel. Tact switches usually have a capacitive touch chip as the core and use touch sensing technology to implement functional operations. It is widely used in various electronic equipment, home appliances, automobiles, smart homes and other fields. It has the characteristics of light operation, quick response, space saving, and beautiful design.
