Abstract
A proximity switch assembly and method for detecting activation of a proximity switch assembly is provided. The assembly includes a plurality of proximity switches each having a proximity sensor providing a sense activation field and control circuitry processing the activation field of each proximity switch to sense activation. The control circuitry controls the activation field of each proximity switch to sense activation, monitors signals indicative of the activation field, and determines a first stable signal amplitude and a subsequent second signal amplitude, and generates an activation output when the second stable signal amplitude exceeds the first stable amplitude by a known amount.
