A proximity switch assembly and method for detecting activation of a proximity switch assembly and calibrating the switch assembly. The assembly includes proximity switches each having a proximity sensor providing a sense activation field and control circuitry processing the activation field to sense activation. The control circuitry generates an activation output when a differential change in the signal exceeds a threshold and distinguishes an activation from an exploration of the plurality of switches. The control circuit further determines a rate of change and generates an output when the rate of change exceeds a threshold rate to enable activation of a switch and performs a calibration of the signals to reduce effects caused by changes in condensation.
