Abstract: An embodiment of an electric heating element is disclosed, including an electrically resistive inner heating element, an electrically resistive outer heating element, and a thermostat positioned underneath a centrally-positioned medallion and along a cold leg of the inner heating element. The thermostat is configured to selectively allow electrical current to be delivered to the inner heating element while maximum electrical current, for example, continues to be provided to the outer heating element. The thermostat cycles the electrical current on and off when detecting maximum and minimum desired temperatures radiated from the electric heating element. The inner heating element has a pair of cold legs that extend parallel to a pair of cold legs of the outer heating element, some or all of which may be supported by a terminal bracket.

Abstract: An electric circuit 100 includes a power line 13 to supply electric power from a power source 11 to a load 12, and a monitor line 14 electrically independent from the power line 13 to detect temperature of the heat source. The monitor line 14 has a breaker 1 connected thereon in series. The breaker 1 includes a fixed contact, a movable piece having a movable contact and pressing the movable contact so as to contact the fixed contact, and a thermally actuated element deforming with temperature changes to actuate the movable piece so that the movable contact is spaced apart from the fixed contact.

Abstract: The present disclosure relates to thermostats. In one illustrative embodiment, a thermostat includes a housing defining a cavity, an electrical contact, a temperature sensitive disc that is configured to transition from a first stable state to a second stable state at a first temperature, and a spring disc having a first stable state and a second stable state. During operation, the temperature sensitive disc may apply a force to the spring disc that causes the spring disc to transition from its first stable state to its second stable state when the temperature sensitive disc transition from its first stable state to its second stable state at the first temperature. The force required to move the spring disk from the first stable state to the second stable state may be less than the force required to move the spring disk from the second stable state to the first stable state.

Abstract: Upper and lower flexible blades carry normally closed contacts that are opened by upward movement of the upper blade responsive to snapping of a bimetal disc. The disc is reset by a pushbutton movable from a rest position to a depressed reset position. In its reset position, part of the reset button extends past the upper blade into engagement with the lower blade for moving and holding the lower contact away from the upper contact to prevent reclosing of the contacts until the pushbutton is moved back toward its rest position.

Abstract: An electric temperature protection switch is provided which has at least two encapsulated contacts in a housing and a current transmission member controlled by a temperature sensing bimetal snap plate. A manual push button device, biased by the force of a reset spring is provided for switching the released switch on again. The switch includes a first bistable snap element directly connected with the transmission member for holding the same in the respective on and off positions. A switch plunger is disposed at a distance from the current transmission member corresponding maximally to the switching stroke of the push button and guided slidably on the switch housing. A second snap element cooperates with the switch plunger and the push button device, which second snap element is moved into a passive position from an active position as the result of actuation of the manual device at critical temperatures, whereby switching of the transmission member from the off to the on position takes place. Greater setting force is provided with respect to the second snap element than with that of the first snap element and a stop is fixed on the housing for the switch plunger for resetting the second snap element from its passive to its active position, with springing back of the spring-loaded push button manual device.

Abstract: A trip-free manual reset thermostat wherein the travel of the reset device is limited so that the disc cannot be moved all the way to its reset position of stability. The reset device engages one side of the cantilever mounted flexible switch arm. Such switch arm is formed with an offset so that the disc-operated bumper engages the switch arm at a point spaced from the line of action of the reset bumper. When reset is attempted while the disc remains at temperatures outside the reset temperature range, the reset device and the disc-operated bumper produce a force couple which tends to maintain the switch in the operated condition.

Abstract: A thermostatic switch comprising a thermal snap-action element which is constraining, and in electrical contact with a spring element. On overheating, the thermal element snaps away from, and releases, the spring element, thereby breaking the electrical circuit. The released or unstrained position of the spring element is spaced from the thermal element in order to prevent electrical contact when the latter returns to its normal position.
