Abstract
A switch combines the benefit of the audible sound produced by ball and spring and metallic contact switches, with the simple, inexpensive, easy to assemble nonmetallic collapsible dome switches. A keycap with an audible lock arm having a ridge thereof for engaging at least one nub formed on the housing is provided allowing the keycap to be moved to at least a first and second position and locked. As the keycap is moved, the ridge moves over the nub producing an audible sound. Inexpensive and easy to assemble collapsible dome structures with electrically conductive pellets carried on an underside are used to close circuits on an underlying substrate.
