Round metal dome: (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 function of metal dome is that when they are placed on the printed circuit board by means of pressure-sensitive adhesive film, in their relaxed state, the metal domes rest on the outer rim of the primary pathway. When pushed, the domes collapse 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.

Many different shapes and tactile forces of our metal domes are available in order to meet customers' applications. All of our metal domes with various choices in shapes,we have the C-series, F-series, T-series, and O-series metal domes, diameter from 3mm to 20mm.We also have the many paltings for the metal domes, such as Nickel plating, silver plating,& gold plating.

No matter what specifications of metal domes you need, we will do our best to produce it. Contact us for more information!!!
