Abstract
A proximity switch assembly is provided. The proximity switch assembly includes a proximity switch comprising a proximity sensor providing an activation field, and control circuitry monitoring a signal responsive to the activation signal and determining an activation of the switch, detecting a first peak value above a threshold when the signal is not stable followed by a drop and a subsequent rise to a second peak value followed by a sharp drop.
