T-Series metal domes (tactile metal domes) are triangle shaped switch contacts that were designed for mounting on double sided PCB and membranes, where a via is run through the circuit board. Applications requiring a minimal diameter switch with an extended contact life, such as small, hand-held devices, are a perfect fit with our T-Series domes.  

The T-Series metal domes (stainless steel domes) are placed on a PCB 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 and make contact with the secondary pathway, thereby closing the circuit.

The T-Series metal domes come in nine different sizes, and can be used anywhere a momentary switch with tactile feedback is required, while still achieving impressive actuation life cycles.

Specification:

The size of T series metal dome from 5mm to 13mm in a range of (trip) force, typical 150- 5600 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.
