An electric closer comprising a first connection lug, a second connection lug electrically insulated from the first connection lug, the first and second connection lugs each having at least one recess in a contact region disposed within a guide housing, an actuator for driving a contact element, the contact element being disposed in a guide housing between the actuator and the contact region of the connection lugs, and by the actuator from an open position, in which the connecting lugs are insulated from one another into a closed position, in which the connecting lugs are electrically connected to one another via the contact element, is displaceable, wherein in the closed position the contact element is accommodated in the recesses of the connecting lugs and wherein the contact element is guided in the displacement direction simultaneously in the respective recesses of the two connecting lugs during the displacement of the two connecting lugs.

Embodiments of the disclosure can include an inertial short-circuit and seismic hook for an electrical equipment disconnect switch.

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.

An electrical switch includes a pivotally supported blade, a toggle mechanism, and an operating mechanism. The operating mechanism is drivable in a first direction to pivot the blade about a first axis and toward a closed blade position. When pivoting toward the closed blade position, the toggle mechanism inhibits the blade from pivoting about a second axis. Upon reaching the closed blade position, continued motion of the operating mechanism in the first direction causes the toggle mechanism to pivot the blade about the second axis toward a closed contact position. In the closed contact position, the blade contacts at least one blade contact to electrically connect the blade and a first electrical terminal.

An electrical switch including a jaw assembly, a housing and a blade assembly. The jaw assembly is electrically connected to a first electrical conductor. The housing assembly is electrically connected to a second electrical conductor. The blade assembly is fixedly attached to said housing assembly at a first end thereof and having an electrically conductive blade contact fixedly attached to a second end distal from said first end. The housing assembly and said blade assembly pivot about a first axis to drive said blade contact into said jaw assembly to close said switch. The blade assembly is operable to rotate about a second axis perpendicular to said first axis only when said distal end of said blade assembly is seated in said jaw assembly.

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.
