摘要： A switch actuator includes an operator plate which provides a structure for mounting the actuator and for supporting the remaining parts. An operator shaft receives torque from an operating handle and via mechanical coupling, transmits torque to a torque plate subassembly. The torque plate compresses a torsion spring which provides temporary energy storage for the switch actuator. The torsion spring acts on a reaction plate subassembly which mechanically couples the torque generated by the spring to a rotor tube to operate the switch contacts. A spring guide subassembly maintains the spring in a predefined region to prevent the spring from deforming into a non-energy storing position during operation. The operator shaft, torque plate, reaction plate, spring guide, and spring are nested substantially concentrically about a predefined mounting axis. Left and right cam followers and a pivot lever combine to form a latch mechanism to prevent the switch actuator from changing position except when operated by a user.

摘要： A plug and socket connector comprises resilient contacts which are adapted to be engaged in bayonet fashion. Electrical contact between each input terminal and a corresponding socket connector-pin is established by coupling two contact studs, one contact stud being carried by a conductive arm rigidly attached to a connector pin, the other being attached to an electrical supply lead. When a plug and socket are disengaged, the contact studs being coupled are positioned in different relative angular positions with respect to the axis of the plug socket. The contact studs are placed into a position of angular coincidence by rotating the plug with respect to the socket. At the end of the rotation of the plug, each arm is subjected to an abrupt pivoting movement in which it is displaced toward an oppositely acting contact stud as a result of a release of the energy stored during the rotation.

摘要： A switching device has: a contact secured to a housing; a movable contact arranged on a contact arm arranged to be movable inside the switching device and including an extension facing away from the movable contact, the movable contact being designed to enter in contact with the contact that is secured to the housing; a breaker mechanism connected to the movable contact arm; a manually operated lever which is connected to the breaker mechanism; and a snap-action closing mechanism including a rotatably mounted snap action rocker which is controlled by a first cam of the manually operated lever and which includes a contact arm-catching unit that is to come in contact with the extension of the contact arm. The contact arm-catching unit preferably has a surface hardness which is greater than or equal to the surface hardness of the extension of the contact arm.

摘要： The potential for an unreliable indication of a tripped overload relay is eliminated in a trip mechanism for an overload relay that includes a housing, and armature mounted in the housing for movement between two contact opening or closing positions, fixed contacts in the housing and moveable contacts engageable by the armature to be moved thereby toward and away from the fixed contacts and. A moveable lever is associated with the armature and is operable to shift the armature from one of the contact opening or closing positions to the other of the contact opening or closing positions. An operator for the lever is moveable toward and away from the lever and carries a spring finger. The spring finger is engageable with the lever to cause the lever to shift the armature between the positions. The spring finger is moveable with the operator in a path from a first position disengaged from the lever to a second position engaged with the lever and then to a third position disengaged from the lever. A cocking surface is carried by the housing adjacent the path to be engaged by the spring finger as it moves from the first position toward the second position to load the spring finger sufficiently that upon the finger obtaining the second position, it will contain sufficient stored energy to cause a shift of the armature.

摘要： A dual energy storage operating mechanism of an isolating switch is provided. A first energy storage mechanism and a second energy storage mechanism are provided between an input wheel and a housing and between the input wheel and an output wheel or a first output shaft, respectively. The output wheel is provided with a limiting mechanism. The limiting mechanism forms a locking effect on the output wheel when the first energy storage mechanism stores energy, thereby enabling the second energy storage mechanism to store energy at the same time. When the first energy storage mechanism starts to release energy, the locking effect of the limiting mechanism is released, so that the output wheel and the first output shaft can rotate, and the first energy storage mechanism and the second energy storage mechanism release energy at the same time, forming a dual energy storage boosting effect.

摘要： A switch includes a base, a support terminal assembled in the base, a movable contact piece made of a belt-like electroconductive material bent into a substantial J-shape in section, a plunger vertically movably accommodated in an internal space, and a coil spring turnably supported by the plunger. The movable contact piece includes a movable contact provided in one end portion thereof An intermediate portion of the movable contact piece is turnably supported by a turning support portion of the support terminal. The internal space is formed by fitting a housing in the base. The plunger is slid while vertically moved press-contact one end portion of the coil spring against the other end edge portion of the movable contact piece such that the movable contact piece is reversed to bring the movable contact into contact with a fixed contact or to separate the movable contact from the fixed contact.
