A switch design for printed circuit cards and boards has a flex disc soldered to the outer edges of the land pattern that provides electrical continuity and also seals the contact surfaces from hostile environments and wet processes. The disc 1, when pressed in the center, will flex and make contact with the land 2 establishing electrical continuity. Releasing the disc will interrupt the circuit.
