The F-Series metal snap domes & tactile snap domes are placed on a PC board by means of pressure sensitive adhesive tape. In their relaxed state they rest on the outer rim of the primary pathway. When metal snap domes are pushed, the centers of the domes collapse and make contact with the secondary pathway, thereby closing the circuit.
The size of F series snap dome is from 5mm to 20mm in a range of (trip) force, typical 125- 500 g. The trip force, rebound/return force, click, travel, and height, etc., can be adjustable according to clients' request.
