ABSTRACT:
A contactless electrical switch includes a switch element comprising a piezo-resistive transducer (25). Coded toothed cams (16) operated via a shaft (14) deflect the transducer (25) causing corresponding changes in stress and hence resistance. The output of the transducer is amplified and fed to logic circuitry which determines a corresponding current path.
