    摘要： A snap acting thermostatic disc assembly having a thermostatic disc element 20 responsive both to current and to ambient temperature is provided with an electrical contact (22) on a face surface on the disc element at one end thereof and a weld slug (24) at an opposite end of the disc element and has a fulcrum member (28, 28', 28") on the opposite face surface of the disc element in alignment with the weld slug. The fulcrum member is arranged to move the bending location of the disc element member away from the heat affected zone of the thermostatic metal caused by welding. In a second embodiment the snap acting disc element is used as an ambient temperature responsive control member.

    摘要： A circuit breaker has two thin flat terminals embedded in an electrically insulating housing exposing respective broad flat sides of the terminals in spaced side-by-side relation to each other in a housing chamber. The circuit breaker has a thermostat metal member secured at one end to one exposed side of one terminal to mount the member extending along a chamber wall and has a contact at its opposite end to engage and disengage the other terminal to close and open a circuit in response to a selected current in the circuit. The contact comprises a material which erodes during repeated cycling of the circuit breaker. The thermostat metal member has a portion of reduced cross-sectional area adapted to burn out and separate the member into two sections to open the circuit if the contact welds or sticks to the other terminal. A stop on the housing intercepts movement of one of the member sections after burn out to avoid shorting of the circuit. An abutment on the housing prevents reclosing of the circuit after the contact has eroded to a selected extent. In one embodiment, an electrical resistance heater of positive coefficient of resistivity having an improved electrical wire insulation is wound on the thermostat metal member and retains the circuit in an effective open circuit condition until the heater circuit is separately interrupted to reset the breaker.

    摘要翻译： 断路器具有嵌入在电绝缘壳体中的两个薄扁平端子，其在容纳室中以彼此间隔开的并排关系暴露端子的相应宽的平坦侧面。 断路器具有恒温器金属构件，其一端固定在一个端子的一个暴露侧上，以安装沿着室壁延伸的构件，并且在其相对端具有触点以接合和分离另一个端子，以闭合并打开电路 响应电路中选定的电流。 触点包括在断路器的重复循环期间侵蚀的材料。 恒温金属构件具有减小的横截面面积的一部分，其适于烧坏并将构件分离成两个部分，以便如果接触焊接或粘附到另一个端子则打开电路。 壳体上的止动器在烧坏之后截取其中一个构件部分的运动，以避免电路短路。 外壳上的支座防止了接触已经侵蚀到一定程度的电路重新闭合。 在一个实施例中，具有改善的电线绝缘的正电阻系数的电阻加热器卷绕在恒温金属构件上，并将电路保持在有效的开路状态，直到加热器电路被单独中断以复位断路器。

    摘要： A thermal protector (1) comprising two fixed contacts (13A, 13B) provided at the end part of conduction terminal pins (5A, 5B) projecting into a metallic enclosed container (100), a support (6) arranged in a case, an oscillatory heating resistor (8) supported by the support and having two movable contacts (9A, 9B) facing the fixed contacts, and a heat responsive body (10) interposed between the heating resistor and the support and coupled with the heating resistor through a coupler (12). When an overcurrent flows through the heating resistor to generate heat therefrom and the temperature of the heat responsive body reaches a set level, the heat responsive body is inverted. Inverting motion of the heat responsive body is transmitted to the heating resistor through the coupler, and the current path is opened.

    摘要： There is provided a switch having a new function for protection from excessive current. The switch includes a conductive movable member (9) and at least two terminals (1, 2, 3). By mechanically moving the movable member (9), the switch can be set to a state that the movable member (9) is simultaneously brought into contact with the two terminals (1, 2) and to a state that the movable member (9) is apart from one (1) of the two terminals (1, 2). At least one (2) of the two terminals (1, 2) is separated into a conductive contact unit (2a) which is brought into contact with the movable member (9) and a conductive connection unit (2c) which is electrically connected to an external element (not depicted). A PTC member (2b) is arranged so as to be sandwiched between the contact unit (2a) and the connection unit (2c). The PTC member (2b) may be a PTC element having a PTC material layer and a pair of conductive material layers arranged on the opposing surfaces.

    摘要： Ein Temperaturwächter (10) mit einem bei Übertemperatur schaltenden Bimetall-Schaltwerk aus Bimetall-Scheibe und stromführender Federscheibe (22) weist einen ersten Heizwiderstand (53) auf, der dem Bimetall-Schaltwerk zugeordnet ist und bei betätigtem Bimetall-Schaltwerk im Sinne einer Selbsthaltefunktion wirkt. Dem Bimetall-Schaltwerk ist ein zweiter Heizwiderstand (54) zugeordnet, der bei zu hohem Stromfluß durch den Temperaturwächter (10) derart wirkt, daß das Bimetall-Schaltwerk schaltet, um so den Verbraucher vor Überstrom zu schützen. Das Bimetall-Schaltwerk ist dabei als Umschalter ausgelegt und so mit den beiden Heizwiderständen (53, 54) verschaltet, daß es in seinen beiden Schaltstellungen jeweils über ein stromführendes Teil (22) den durch den Temperaturwächter (10) fließenden Strom übernimmt.
