E-Series Oblong

Our E-Series Oblong metal tactile domes are oblong shaped switch contacts that were designed for mounting on printed circuit boards, flex circuits, and membrane circuitry. Applications such as “space bar” keys are a perfect fit with our E-Series Oblong domes. The E-Series Oblong 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 E-Series Oblong 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.
