E-Series Round

Our E-Series Round metal tactile domes with feet are round shaped switch contacts with a dimple in the center that were designed for mounting on printed circuit boards, flex circuits, and membrane circuitry. The E-Series Round domes come in four different sizes, and can be used anywhere a momentary switch with tactile feedback is required, while still achieving impressive actuation life cycles. The E-Series Round 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.
