ABSTRACT:
A key switch comprises a disc-shaped switch contact suspended above a number of stationary terminals. The switch contact includes one or more cut-outs which isolate individual terminals in different angular orientations of the contact. The signals conducted through each terminal vary as different combinations are bridged by the contact in different angular orientations. By changing the pattern of the cut-outs through the contact, the signals conducted through the switch are changed. The switch is efficient to produce because it can be adapted to different circuits without substituting physically different terminal pieces.
