The O-Series metal domes (stainless steel domes, or tactile metal domes) are small, oblong shaped switch contacts that were designed for mounting on single or double sided PCB 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. The O-Series metal domes can be used anywhere a momentary switch with tactile feedback is required, while still achieving impressive actuation life cycles.
O-Series 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.
Specification:
The size of O 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.
In addition to our wide range of standard metal dome, we also offer the ability to design any custom metal dome your application may need. Whether you need a custom size, shape, trip force, rebound/return force or travel, we will work according to your design/drawing/samples to provide the exact metal dome for your application.
Do you have a competitors part number and aren't sure if we already make that particular metal dome (or named metal snap dome or tactile dome)? Please contact us and send us the details, so that we may assist you in what you are searching for.
