摘要： The present invention provides a plug with overload protection and a safety switch. It is comprised of an upper case, a bottom case, two conductive polar plates, two connective plates, two alloy plates, a safety switch, and a return spring. The main features are as follows: the end of one conductive polar plate is joined with an alloy plate by mortise and tenon joint, while the other alloy plate, located on the rear end of the said plate, is joined with the front end of the connective plate by mortise and tenon joint. Then it will become electric connected. Also, the protruding insulating plate that on the bottom of the upper safety switch is just located on the top of the gap between the two alloy plates. When the circuit is short-circuited or overheated due to overload, the two alloy plates will be expanded and outstretched relatively to allow the return spring in the other end of the switch to push the insulating plate into the gap between the two alloy plates to cut the circuit between them with one of the features of the present invention, called the safety switch, which is equipped with automatic circuit breaker protection for the sake of safety.

摘要： A circuit breaker includes a nonconductive housing, a first breaker contact within said housing, and a trigger element having a second breaker contact located within said housing. The trigger element is thermally activated to separate the first and second breaker contacts in an overcurrent condition. A nonconductive reset mechanism is located in the housing and configured for sliding actuation to prevent electrical connection between the first breaker contact and the second breaker contact after the trigger element has activated.

摘要： A circuit breaker switch essentially comprising a push button switch, an alloy metal having one end connected to a contact of a circuit of the switch and the other end being mounted to the circuit of the switch. If the current to the switch does not exceed a predetermined current value, the switch functions as a normal switch. That is, the original position of the switch is in the “OFF” position and a depression to the push button changes its position to the “ON” state. A further depression of the push button restores the push button to the “OFF” state. When the current passed to the switch exceeds the predetermined current valve, the alloy metal is thermally deformed and curved upward, which forms a gap to allow an insulating plate to be inserted to cut off the current supply and open the circuit. The switch restores to its function by resetting the push button.

摘要： A plug with security device, including a housing, several conductive insertion plates adapted to be inserted into a power socket, conductive wires connected to an electric appliance and a security device. The insertion plates are connected with the conductive wires in the housing. The security device is disposed between at least one insertion plate and one conductive wire and includes a casing, a disconnector seat disposed therein, a thermal bimetal blade disposed on the disconnector seat, a movable contact disposed on the bimetal blade, a fixed contact disposed in the casing and connected with the conductive wire to naturally contact with the movable contact, and an insulative separating structure. When an excessively large current passes through the electric appliance, the bimetal plate is bent to separate the movable contact from the fixed contact and open the circuit. At this time, the insulative separating structure is inserted into a space between the movable and fixed contacts so as to keep the circuit open.

摘要： An improved safety switch with overload protection circuit includes a housing having a lamp cover and three connecting plates disposed in a receptacle. One connecting plate is provided with a bi-metal plate having a platinum contact, and one is provided with a platinum contact corresponding to the bi-metal plate. When power is overload, the bi-metal plate will trip off so that an electrically insulating baffling plate may slip in between the platinum contacts to cut off power supply. The lamp cover is provided with a control hook which may control the bi-metal plate. The lamp cover further has a leg extending into an elongated notch of the baffling plate. By pressing the lamp cover, displacement of the bi-metal plate and the baffling plate may be controlled to achieve electrical connection or disconnection.

摘要： This invention relates to a circuit breaker switch having a cover, a housing, two copper plates, a bimetallic blade, a push button and a push rod, wherein the bimetallic blade acts as a bridging contact between the two copper plates at a rated current to conduct electricity. When there is a current overload, the bimetallic blade, because of its character, will bend and depart from the two copper plates to cut off current. The circuit may be open even if the current is not at an overload value by a user pushing the push rod inwardly to separate the bimetallic blade from the two copper plates when necessary. The contact points of the two copper plates are caused to stay in a switch-disengaging position by action of an insulating plate.

摘要： The invention relates to a contact breaker of the type that includes a slider (22, FIG. 1) that slides longitudinally within a housing to allow a moving contact 50 (FIG. 3) on a sudden actin bimetal strip (44) to pass through a slider opening (62) against a fixed contact (40), or to keep the contacts apart after they have briefly moved apart. The state of the contact breaker is indicated by a signalling electrical circuit which includes a moving contact (80, FIG. 1) mounted on the slider and having a pair of clips that connect coplanar signalling contacts (68, 70). The slider has a lower extension (92, FIG. 4) that prevents arcing between power contacts. The housing includes two half-casings (16, 18, FIG. 7) joined at a longitudinal joint 19, one carrying power terminals (32, 34) and the other carrying signalling terminals (74, 76). The slider keeps the contacts (50, 40, FIG. 3) separate even if the front housing surface is blocked.
