An apparatus and method for restricting the rotation of a dial control knob on the high setting of an electric cooking range using one of three methods. The first method adds a detent stop internally to the switch. The second method adds a detent stop externally attaching to the control panel behind the top burner knob. Both of the aforementioned methods are designed to prevent rotation of the control knob to a maximum of 227° rotation. A third limits the on/off cycling of the top element switch while in operation to reduce the overall output of the switch.

A semiconductor device is disclosed. The semiconductor device includes a semiconductor substrate, and a heater element on the semiconductor substrate, the heater element configured to generate heat in response to a current flowing therethrough. The semiconductor device also includes a conductor material having a programmable conductivity, and an insulator layer between the heater element and the conductor material, where the conductor material is configured to be programmed by applying one or more voltage differences to one or more of the heater element and the conductor material, and where a capacitance between the conductor material and the heater element is configured to be controlled by the voltage differences such that the capacitance is lower while the conductor material is being programmed than while the conductor material is not being programmed.

Disclosed is a flash double-temperature linkage temperature controller, comprising a mounting plate (1), and a mounting column (2) provided on the mounting plate, wherein a temperature-sensing bimetal sheet (3), a ceramic ring I (4), a static contact sheet set I (5), a ceramic ring II (6), a movable contact sheet set I (7), a ceramic ring III (8), a static contact sheet set II (9), a ceramic ring IV (10), a movable contact sheet set II (11), and a ceramic ring V (12) are sequentially mounted to the mounting column from top to bottom, and a linkage rod (15) is provided between the movable contact sheet set I and the movable contact sheet set II. According to this technical solution, the traditional single circuit is changed into two circuits; the two movable contact sheet sets and the two static contact sheet sets are connected via the linkage rod and a ceramic column II; contacts of the two movable contact sheet sets and the two static contact sheet sets sequentially operate at different temperatures due to the design of the height of the ceramic column II; and a desired fixed temperature difference is obtained. The two movable contact sheet sets are respectively connected to the two static contact sheet sets to control two electric heating tubes, so that the effect whereby two electric heating tubes (high power) work during water heating and a single electric heating tube (low power) works during hear preservation heating is achieved, and the working frequency of the high-power contact sets is greatly reduced.

A breaker 1 includes a fixed piece 2 having a fixed contact 21, a movable piece 4 including a movable contact 41 and having the movable contact 41 so as to be pressed against and in contact with the fixed contact 21, a thermally actuated element 5 shifting the movable piece 4 from a conductive state to a cut-off state in accordance with a temperature change, and a case 7 accommodating the fixed piece 2, the movable piece 4, and the thermally actuated element 5. The case 7 includes a case main body 71 accommodating the movable piece 4 and the thermally actuated element 5, a lid member 81 covering a housing concave portion 73 of the case main body 71, and a metal plate 9 embedded in the lid member 81. Heat capacity of the metal plate 9 is larger than heat capacity of the fixed piece 2.

A temperature-controlled device for switching off a heating device at a limit temperature has a thermo-mechanical temperature sensor device, a switch-off device, and manual reactivation means. The switch-off device has switching means which are activated by a trigger for switching off the heating device. The manual reactivation means have a movable handle and transmission means for transmitting a force of an operator for reactivating the switching means after switching off the heating device by the trigger. The transmission means have a click spring which at the beginning is in a basic position and, when an operating force acting on said click spring exceeds a certain limit force, clicks to a deflected position. Said click spring in the basic position enables reactivating or re-switching on, respectively, of the switching means. Said click spring in the deflected position releases so much movement path on the transmission means for the switching means that said switching means by the temperature sensor device and by the switch-off device above the limit temperature are activatable and switchable by the trigger.
