A temperature responsive switch includes a housing, an actuator arm for movement in response to temperature conditions, a movable contact, and an adjustable contact connected to a defrost terminal for completing a defrost circuit on demand without requiring a separate switch. The movable contact engages and disengages the defrost contact to cycle a defroster on and off in response to temperature changes in an evaporator tube, and also engages a stationary contact to complete a compressor circuit and cycle a compressor on and off in response to changes in an evaporator tube.
