F-Series

Our F-Series metal tactile domes are four-legged switch contacts that were designed specifically 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. They come in nine different sizes, and can be used for contact or tactile element only. The F-Series 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.
