Abstract
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 auxiliary terminal for completing an auxiliary circuit. The movable contact engages and disengages the auxiliary contact to cycle a first element on and off in response to exceedingly large temperature swings a specified location, and also engages a stationary contact to complete a main circuit and cycle a different electrical element on and off in response to relatively modest changes in temperature changes at the same specified location.
