<p>An electrical switch (10) includes an insulative substrate (12) having lower conductive circuitry (14) supported thereon. The circuitry includes a plurality of switch contacts (22) and a plurality of leads (24) for connecting the switch contacts to appropriate conductors. A stamped metal sheet (16) is disposed over the insulative substrate (12) and includes a plurality of embossed metal domes (44) in registry with and spaced from respective ones of the switch contacts (22). Depression of a selected one of the embossed metal domes (44) engages the dome with a respective one of the switch contacts (22) to close a circuit therethrough. <IMAGE></p> |
