A compact, lightweight and low-cost operating apparatus for a switchgear include a second cam (50) turned counterclockwise by an electric motor begins to maintain contact with a closing lever (37) at a first angular position (POS1), turns the closing lever (37) counterclockwise to energize a circuit-making coil spring (77), and causes a closing latch (48) to lock the closing lever (37). The second cam (50) further turning counterclockwise becomes separated from the closing lever (37) and actuates a cam switch (156) at a second angular position (POS2) to interrupt an electric current supplied to the electric motor. The second cam (50) further turns due to inertial turning of the electric motor and is braked by a elastic brake member (159) at a third angular position (POS3), whereby the second cam (50) stops within a specific angular range DELTAtheta of rotation. Despite its simple structure, the elastic brake member (159) can halt the second cam (50) in a reliable fashion.

A vehicle switch includes a case having a through-hole through the top face thereof, an operating body, a switch contact, an elastic cover, and a sliding part. The top end of the operating body projects from the through-hole. The operating body is housed in the case vertically movable. The switch contact is brought into and out of electrical contact by the vertical movement of the operating body. The elastic cover covers the through-hole of the case and the top end of the operating body. The sliding part that has a smaller friction coefficient than that of the elastic cover is provided in the top portion of the elastic cover, and covers at least the rim of the top portion of the elastic cover, or protrudes from the top face of the top portion and has an arc-shaped curved surface in the outer periphery of the upper rim thereof.

A plunger switch for use as a switch element in an electrical circuit, has a housing and a plunger movable axially in a bore of the housing in the direction of a longitudinal axis and when in an operating position in which it is depressed toward the housing, acts on an electronic sensor unit situated in the housing, which in turn initiates a switching procedure in the electrical circuit by electrical pulses, and the plunger, in its axial plunging region into the bore of the housing, is peripherally provided with at least one lubricating groove, which permits a lubricating fluid to travel into the axial plunging region between the plunger and bore, and the electronic sensor unit is protected from a penetration of lubricating fluid.

The invention discloses an electrified lubricating device for an isolating switch. The electrified lubricating deice comprises an oil pump system, a first oil tube, a second oil tube, an insulating tube and an oil nozzle, wherein the oil pump system comprises an oil storage pot and an oil pump, and the oil storage pot is connected with an oil inlet of the oil pump by virtue of the first oil tube; and the oil nozzle is connected with one end of the insulating tube, one end of the second oil tube is connected with an oil outlet of the oil pump, and the other end of the second oil tube extends into the insulating tube and is connected with the oil nozzle. The electrified lubricating device disclosed by the invention can be used for adding a lubricant to a transmission part of the isolating switch in an electrified manner, and by virtue of periodical lubrication, the problems that unsmooth blockage caused by the reason that the isolating switch is not operated and overhauled for a long time is generated, and the isolating switch and a ground switch cannot be connected and disconnected in place and cannot be connected and disconnected are greatly eliminated, so that the running reliability and power supply reliability of the isolating switch are improved, and the economic benefit of an enterprise is improved; and by using the electrified lubricating device disclosed by the invention, climbing operations of maintenance personnel can be avoided, and thus the safety risk of the maintenance personnel can be reduced.
