The Circle Dome Family (including with dimple and without dimple) is designed specifically for membrane, switches & tactile feeling applications, which is designed for over-travel applications.

C Series metal domes(tactile metal domes, or metal snap domes) are round shaped switch contacts that were designed for mounting on membrane circuitry. They are designed to be pushed past the flat plane by .005-.010" for optimal tactile feedback. The C-Series domes will not invert when pushed past the flat plane. Applications requiring a low profile switch under a membrane overlay are a perfect fit with our C-Series metal domes. It can be used anywhere a momentary switch with tactile feedback is required, while still achieving impressive actuation life cycles.

The C-Series metal domes (round metal dome switches) 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 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. No matter what size or force you require, we'll do our best to produce it.
