RK-Series

Our RK-Series metal tactile domes 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 RK-Series domes. The RK-Series 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 RK-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.
