An electrical switch is disclosed for switching an electric current, the switch being suitable for being inserted into a switch holding device. In at least one embodiment, the switch includes a locking device which, in the event of an overcurrent, moves a locking element of the locking device to a position which mechanically locks the switch in the switch holding device.

Electrical switch

One embodiment of the present invention relates to a coupling arrangement for transmission of the rotational movement of a switching shaft of an electrical switch to at least one position signalling device including a mount and including at least one coupling, which is mounted on the mount so that it can rotate, via which the switching shaft is mechanically operatively connected to a device for operation of the at least one position signalling device, when the electrical switch is in the test position or in the operating position. In order to simplify the physical design, an embodiment of the invention provides that the mount be provided with a bayonet contour and that the coupling be provided with at least one bayonet projection, such that the coupling is connected to the mount in the form of a bayonet fitting by means of a plugging-in movement followed by a rotary movement, and that a stop device be arranged on the mount, limiting the movement path of the coupling, which is connected to the mount, to its rotary movement.

Switch activated slide linkage

At least one embodiment of the invention provides that, for a closing apparatus for a part rack withdrawable via V-shaped rod assemblies, the closing apparatus includes at least one pin formed on rod assemblies or as part of them, each pin engaging in a slot in an actuating element. Owing to the use of the slots, the actuating element can be formed as a rigid body, with the result that no frictional forces need to be overcome when inserting a circuit breaker into a withdrawable-part rack with the closing apparatus according to at least one embodiment of the invention. With the closing apparatus according to at least one embodiment of the invention, a locking element can have a particularly simple design: it can be guided in the actuating element.
