The present disclosure discloses a special-purpose ground fault circuit breaker, belonging to the technical field of sockets, which comprises at least two conductors, a socket box, a testing mechanism, a reset mechanism and a grounding connector, wherein the at least two conductors are electrically isolated, the reset mechanism comprises a moving arm, the moving arm and a power input terminal form one of the conductors, a socket silver point forms the other conductor, and the socket silver point and the power input terminal are fixedly installed in the socket box. The structure mechanism is simple, simplifying the internal structure of a leakage protection socket, reducing the manufacturing cost of the leakage protection socket, and reducing the manufacturing procedures.

Circuit breakers with handles having at least one handle bearing pin that contacts an upper end portion of a moving arm and allows the arm to rotate to “OFF”, “ON” and “TRIP” positions, typically about 90 degrees of rotation.

A particularly reliable quick release latch and a release mechanism, as well as a quick grounding device or short circuiter, is particularly suited for low, medium, and/or high-voltage applications.

An electrical outlet receptacle including a circuit board defining a first plane and a solenoid having a central axis perpendicular to the first plane. The electrical outlet receptacle further including a reset plunger with a portion extending through the first end of the solenoid and axially movable therein, and an armature movable axially along the portion of the reset plunger extending through the solenoid. Wherein the armature includes a slanted projection configured to contact a cam surface of a slide mechanism and provide the downward force on the cam surface.

An electrical overload protection device for readily identifying and resetting a tripped circuit breaker includes a button, which is retained in depressed and extended configurations by a biaser. A first end and a second end of a plate spring are attached to the housing and the biaser, respectively. A bimetal strip, which is attached to and positioned in the housing, is reversibly deformable and thus bendable upon exposure to a specified current. Depressing the button contacts the biaser with the bimetal strip to complete an electrical circuit, which, should it exceed the specified current, bends the bimetal strip to actuate the plate spring to extend a shaft from the housing. The bending also disengages the biaser from the bimetal strip and breaks the electrical circuit. Depressing the shaft reverses deformation of the bimetal strip and reextends the button so it is again depressible to complete the electrical circuit.

A power switch including a line input configured to receive a line voltage, a load output configured to output the line voltage, and a contact configured to selectively electrically connect the line input to the load output. The contact has a closed position in which the line input is electrically connected to the load output, and an open position in which the line input is not electrically connected to the load output. The power switch further includes a switch configured to selectively control the contact between the open position and the closed position, a housing, and a mounting foot configured to secure the housing to a surface. The mounting foot includes a molding and an insert contained within the molding.

An electrical outlet receptacle including a circuit board, a set of fixed contacts and a set of movable contacts, a solenoid, a carriage, a lifting shelf, a slide mechanism, a reset plunger, and an armature.

A particularly reliable quick release latch and a release mechanism, as well as a quick grounding device or short circuiter, is particularly suited for low, medium, and/or high-voltage applications.

Described herein is a low voltage switching device including: one or more electric poles having one or more movable contacts and corresponding fixed contacts adapted to be coupled to or uncoupled from each other; a movable contact assembly including said movable contacts and a main supporting and operating shaft reversibly movable between a first contact position, at which said movable contacts and said fixed contacts are uncoupled, a second contact position, at which said movable contacts and said fixed contacts are coupled, and a third contact position, at which said movable contacts and said fixed contacts are coupled and kept pressed; an operating assembly including a handle mechanism having a handle adapted to be reversibly moved by a user or a motor operated actuator (MOE) between a first, open position and a second, closed position; and a driving assembly operatively connected to said operating assembly.

An operating mechanism of a circuit breaker, wherein two ends of a first spring are rotationally connected to a rocker arm assembly and a first crank through a first spring shaft and a second spring shaft respectively, and one end of a jump buckle is rotationally connected to a bracket and is a jump buckle pivoting end; a jump buckle hole of the jump buckle is aligned with a bracket hole of the bracket; the first spring shaft is in limiting fit with the jump buckle; and one end of the first crank swings in a direction away from the jump buckle pivoting end, such that a spacing between the first spring shaft and the second spring shaft is smaller than or equal to the length of the first spring, and a first assembly state is formed.
