摘要： A thermal trip assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, separable contacts enclosed by the housing, an operating mechanism for opening and closing the separable contacts, and a number of shunts. The thermal trip assembly includes a load conductor, a bimetal adapted to cooperate with the operating mechanism to open the separable contacts in response to a trip condition, and a bypass heater element structured to be electrically connected to the shunts. The bypass heater element directs the flow of electric current to at least partially bypass the bimetal.

摘要： A switch includes a switch member and an extension and a push rod respectively extended from two ends of an underside of the switch member. A bimetallic contact plate has a first end fixed to one of two terminals and a contact portion splits from the contact plate. A first contact point is connected to an underside of the contact portion and a second contact point is connected to the other terminal. A free end of the contact portion is connected with a free first end of a spring member and a second end of the spring member is connected to the contact plate. When overload, the contact portion and the spring member move upward to cut off the circuit while the push rod extends through a through hole defined in the spring member.

摘要： A switch device includes a body with switch pivotably connected to a top thereof and two terminals extend through an underside of the body. A first contact point is connected to one of the terminals and a bi-metallic plate has a first end fixed to the other terminal. A second contact point is connected to an underside of a second end of the bi-metallic plate and located above the first contact point. A pull member has an upper end pivotably connected to the switch member and a lower end of the pull member supports the underside of the second end of the bi-metallic plate. An upper end of a push member is pivotably connected to the switch member and a lower end of the push member is in contact with the bi-metallic plate. A spring is biased between the push member and the body so as to provide a push force to the push member. A board movably received in a recess in an inside of the body and movable by an adjusting member extending through a hole through the body. A biasing member has a first end connected to the second end of the bi-metallic plate and a second end of the biasing member is engaged with the board. The biasing force of the biasing member relative to the bi-metallic plate is adjusted by moving the adjusting member.

摘要： In one embodiment of the present invention, a temperature sensitive tip switch comprises a first conductive arm, a second conductive arm disposed in a parallel, spaced apart relation beneath the first conductive arm, a third conductive arm disposed in a parallel relation beneath the second conductive arm, and a temperature sensitive actuator blade disposed in a parallel, spaced apart relation beneath the third conductive arm. The second conductive arm includes a cut-out portion which is capable of downward flexion and the third conductive arm includes a cut-out portion which is capable of downward flexion and which is engaged with the cut-out portion in the second conductive arm. A first pair of normally closed, electrical contacts are mounted on the actuator blade and the third conductive arm. A second pair of normally closed, electrical contacts are mounted on the second conductive arm and the first conductive arm. In use, an adjustable thermostat shaft assembly is disposed to contact and selectively urge the cut-out portion in the second conductive arm in a downward direction so as to open the first pair of electrical contacts in a fast-action manner. In addition, an insulated button is mounted on the actuator blade and is disposed to contact and selectively urge the third conductive arm upwards upon the application of heat so as to open the first pair of electrical contacts in a fast-action manner. Furthermore, a gravity sensitive tip-over device is mounted on the actuator blade and is disposed to selectively urge the first conductive arm away from the second conductive arm upon a change in the orientation of the switch so as to open the second pair of electrical contacts.

摘要： A user adjustable switching controller for duty cycle regulating flow of current to an electrical load such as a resistance heater, particularly for cooking appliances. A load current switch, when closed by a user operated cam also energizes a heat motor which includes a resistive strip attached to one active leg of a U-shaped bi-metal member. The load current switch snap spring is attached to the heated leg of the bi-metal. The other leg of the U-shaped bi-metal is anchored to one of the load connecting stationary terminals and serves to provide ambient temperature compensation. User rotation of the cam deflects a bias spring which acts on the portion of the bi-metal attached to the load switch snap spring to effect closing of the load current switch and energization of the heat motor. Heating of the bi-metal causes warpage which overcomes the bias spring to open the load switch and shut off the heat motor. Cooling of the bi-metal allows the load current switch to re-close repeating the cycle. User adjustment of the cam varies the bias on the snap spring and thus the re-open point of the switch with respect to the cycle, thereby varying the ratio of "on" to "off" time of the load current.

摘要： An adjustable thermostat range limit apparatus consists of a base member having a pair of adjustable temperature limit means. The thermostat range limit apparatus is attached in the proximity of a conventional thermostat so that the adjustable temperature limit means can come into contact with the temperature control level of a conventional thermostat. These adjustable temperature limit means will provide for a restriction in the temperature range in which the temperature control lever can be set.

摘要： A thermostat having a simple to see and use setup-setback visual indicator. One temperature control is used to set temperature while a second temperature control is used to activate the setup or setback. The second temperature control is offset from the body of the thermostat in the setup or setback mode to provide simple visual indication of the setup or setback.
