A push button switch has a housing, a switch actuator movably supported by the housing, an organic light emitting diode display supported by the housing in a position to be viewable by a user of the push button switch, and a switch supported by the housing so as to operable by the switch actuator when the switch actuator moves relative to the housing. A controller circuit is electrically coupled to the push button switch so as to control the organic light emitting diode display in response to operation of the switch.
