ABSTRACT:
A unitary assembly includes a thermostatically controlled valve and an electric switch coupled for operation therewith. Both the valve and the electric switch are operated under the control of a thermostatic actuator which effectuates operation through a snap acting member movable between alternate stable positions. Neither the valve nor the electrical switch can dwell at the threshold of actuation, but rather are positively actuated to either an open or closed position when the snap acting member moves to one of its stable positions, and to an opposite condition when the snap acting member moves to its alternate stable position. The movement of the thermostatic actuator can be adjustably multiplied by a lever arrangement in the valve housing. The movement of the snap acting member can also be multiplied by an internal arrangement employing a lever ring with radially inwardly directed cantilevered lever arms. The valve of the invention may be employed for direct actuation of ignition of a gas burner, for actuation to open a flue damper, and for actuating a burner and a blower in a forced air combustion chamber.
