The C-Series metal domes are placed on a membrane switch by means of pressure sensitive adhesive tape. In their relaxed state they rest on the outer rim of the primary pathway. When they are pushed, the centers of the domes collapse past the flat plane and make contact with the secondary pathway, thereby closing the circuit.
The Circle Metal Dome Family (No Dimple) is designed specifically for membrane, switches & tactile feeling applications, which is designed for over-travel applications. The Round Dome Family (Dimple) is designed specifically for mounting on printed circuit boards. They can also allow different applications including membrane, switches & tactile feeling applications.
The size of C Series metal dome is from 4mm to 20mm in a range of (trip) force, typical 100- 500 g. The trip force, rebound/return force, click, travel, and height, etc., can be adjustable according to clients' request.
