Metal Domes Switch Domes Switch ---- Oblong Series

Our O-Series metal dome switches & dome switches are small, oblong shaped switch contacts that were designed for mounting on single or double sided printed circuit boards, flex circuits and membranes, where traces can be fed under the domes on the same side of the board. Applications requiring a low profile switch on an overly populated circuit board are a perfect fit with our O-Series metal domes switches. Oblong-Series metal domes switches & dome switches come in three different sizes, and can be used anywhere a momentary switch with tactile feedback is required, while still achieving impressive actuation life cycles. 


The O-Series metal dome switches & metal 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 they are pushed, the centers of the domes collapse and make contact with the secondary pathway, thereby closing the circuit. 

The size of O Series metal dome switches & tactile dome switch 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. 

OEM is available. No matter what size or force you require, we'll do our best to produce it. Contact us now for more!
