Abstract

A compact device for the manual control of operating switches, comprising a handle (11) mountable on a wall of switchgear containing a switch operated by rotating a rod (20) provided with projecting elements (21) which is able to be removably connected to an inner portion of the handle and is rotatably associated with a baseplate (12), the rod being rotatable from a position in which internal electrical contacts are open and in which it can be released from the handle, to a position in which the internal electrical contacts are closed and in which it is locked to the handle. Within the body of the handle there is provided an aperture (19) arranged to receive the rod and the projecting elements, on the baseplate there being positioned an elastic (35) element which is aligned with the aperture and with the extensions provided in the handle when the baseplate is in a first position, and is superposed on and engaged with the rod and the projecting elements contained in the extensions when in a second position. The baseplate is recessed and is closable by a cover element which is also provided with an aperture for the passage of the rod and the projecting elements. <IMAGE>
