A locking structure of switch device includes a connection seat formed with a main body assembling hole. An arm protrudes from the connection seat. A restriction section is formed on the arm. A shift body is assembled on the connection seat and movable between a first position and a second position. The shift body has a shift section aligned with the arm in the second position. A lever member is disposed on the shift section. Two ends of the lever member are respectively formed with a ridge section and a push/press section. When the shift body moves from the first position to the second position, the ridge section passes over the restriction section into a locked state. When pressing the push/press section, the ridge section is driven by way of leverage to backward pass over the restriction section into an unlocked state.

A switch extension device comprises an elongate extension member and an actuation member. The elongate extension member has a distal end shaped to couple with an electrical switch and a proximal end for positioning remote from the electrical switch. The actuation member is coupleable to the proximal end of the elongate extension member. The actuation member is movable to move the extension member to actuate the electrical switch. Methods of operation are also described.

The invention relates to an electrical switching device, in particular a position switch, limit switch, microswitch or other limit stop switch, having at least one housing and one or more electrical switch contacts arranged in the housing, the housing having at least one actuation opening, via which the switch contact(s) can be actuated mechanically from a position outside the housing, the switching device, as a further separate component, having at least one actuator, which has at least one actuation ram that is longitudinally displaceable in the direction of a longitudinal axis of the actuator, the actuator, in a number of different rotation angle positions with regard to the longitudinal axis, being securable to the housing of the switching device in a manner secured against rotation, in such a way that, in the event of external actuation of the actuation ram, the switch contact(s) can be mechanically actuated, a strap being provided as securing means to mechanically secure the actuator to the housing of the switching device, which strap can be slid over at least part of the actuator and at least part of the housing of the switching device.

The present invention relates to an on-off lever of a disconnecting switch for a power distribution line that can connect or disconnect lines through easy and safe manipulation of the on-off lever. According to an embodiment of the present invention, the on-off lever of the disconnecting switch for the power distribution line, the on-off lever having: a lever body mounted to an end part of a movable member; a shaft hole formed on a first portion of a middle part of the lever body; a locking step provided on a lower part of the lever body such that the locking step is locked to a locking end; a guide hole formed on a second portion of the middle part of the lever body; and a manipulation means provided on an upper part of the lever body.

A high voltage, high current, switching device includes a jaw assembly electrically connected to a first electrical conductor, a housing assembly electrically connected to a second electrical conductor and a blade assembly fixedly attached to the housing assembly at a first end thereof. The blade assembly has an electrically conductive blade contact fixedly attached to a second end distal from the first end. Further, the housing assembly and the blade assembly pivot about a first axis to drive the blade contact into the jaw assembly to close the switch and the blade assembly is operable to rotate about a second axis perpendicular to the first axis only when the distal end of the blade assembly is seated in the jaw assembly. Thus, the blade does not pivot about its longitudinal axis prematurely, for example, before it is properly seated in the electrical terminal.

A contact system of a circuit breaker includes a fixed contact. The contact system also includes a moveable contact arm assembly comprising at least one moveable contact arm having a moveable contact thereon, the moveable contact arm moveable to define a closed condition and a blow open condition. The contact system further includes a carrier assembly operatively coupled to the moveable contact arm. The contact system yet further includes a latch plate operatively coupled to the carrier assembly. The contact system also includes a trip shaft operatively coupled to the carrier assembly, the trip shaft having a non-circular region defining an engagement surface disposed in contact with the latch plate in the closed condition. The contact system further includes a biasing portion of the moveable contact arm configured to rotate the trip shaft out of engagement with the latch plate and into the blow open condition.

A blade assembly for an electrical switch. The blade assembly including a rocker assembly configured to enable rotation of said blade assembly. The rocker assembly including: a first rocker component, said first rocker component having a first rocker pin, and a second rocker component, said second rocker component having a second rocker pin that depresses when said first rocker pin is depressed.

An air break switch including a first insulator and a second insulator opposite the first insulator. The second insulator including a blade, wherein the blade is configured to rotate about a first axis parallel to the second insulator and about a second axis perpendicular to the second insulator.
