Abstract
An electrical switch assembly includes a member by which a user selects one of a plurality of functions. Operation of the member applies different amounts of pressure to a transducer that has an impedance which changes in response to the applied pressure. An input circuit produces an output voltage which varies in relation to changes in the impedance of the pressure transducer. A voltage comparator compares the output voltage to a plurality of voltage ranges and in response to the voltage comparison, an output driver produces at least one electrical signal that indicates which one of plurality of functions the user has selected.
