U-Series

Our U-Series metal tactile domes are four-legged 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. What differentiates the U-Series from other four-leg metal domes is the increased tactile response when actuated. Applications requiring a higher tactile feedback than our F-Series domes are a perfect match for the U-Series domes. The “Ultra Snap” domes 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 U-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.
