Keyboard switch assembly having foldable printed circuit board, integral spacer and preformed depression-type alignment fold

Claim 1

A keyboard component for a keyboard comprising a unitary sheet of flexible and resilient insulator plastic having first and second sections supporting contactors and contacts respectively and a tail section supporting terminals, said first section having protrusions supporting at least some of said contactors, said sections being disposed to one another in an L configuration with said first section forming one leg of said "L" and said tail section and said second section forming the other leg of said "L," said first section being foldable over said second section to align said contactors with said contacts, a contactor of an on-off switch supported by said first section, a contact of an on-off switch supported by said second section, said contactor and contact spaced substantially equidistant from the intersection of the legs of the L, a first circuit line supported by said first, second and tail sections, and extending across said intersection of the legs of the L, a second circuit line adjacent said first circuit line and supported by said second and tail sections, said first circuit line coupled to said contactor and said second circuit line coupled to said contact, and terminals supported by said tail, one terminal coupled to each circuit line and actuator means movable between on and off positions to cause said contactor to engage said contact when said actuator is in said on position.
