Abstract

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.
