ABSTRACT:
An electrical switch includes a generally planar, generally stiff dielectric substrate. Stamped sheet metal circuitry is engaged to at least one side of the substrate and includes an open circuit portion. A layer is juxtaposed over the circuitry and includes at least one contact area on a side of the layer in facing relation with the open circuit portion. Therefore, movement of the layer toward the substrate is effective to move the contact area and close the open circuit portion. Preferably, the dielectric substrate is insertmolded about the stamped circuitry. The circuitry includes bent spring beams for mounting to appropriate conductors. The invention also contemplates a method of fabricating the electrical switch as well as a circuit frame incorporating the stamped circuitry and the insert-molded substrate.
