Movement of the diaphragm pad occasioned by change in pressure within the diaphragm in response to a change in sensed temperature causes the bowed actuating spring to increase or decrease the degree of flexure to actuate the switch. In order to accommodate the pressure variations induced by a wide range of ambient temperature conditions the diaphragm is preloaded by a second bowed spring. A cam mechanism can be provided to vary the flexure of the preloading spring to thereby adjust the temperature at which the switch will be actuated.
