An adjustable bimetal snap disc thermostat is disclosed in which a leaf spring acts at its center to apply a force to a bimetal snap disc to alter the operating temperature thereof. The force of the spring applied to the disc is adjusted by an operating member which simultaneously moves both ends of the spring with respect to its center. The operating member is located on the side of the thermostat switch remote from the disc and is provided with projections which extend around opposite sides of the switch to the spring. With this structural arrangement, small adjustment travels are required for a given adjusting spring and the thermostat is constructed in a compact manner, which is symmetrical about the center axis of the device.
