UNIT FOR CONTROLLING BLOCKED SOCKETS Russian patent published in 2011 - IPC H01R13/707 H01H9/16 H01H19/00 

FIELD: physics, communications.

SUBSTANCE: invention relates to a unit for controlling blocked sockets. The disclosed device has a visual display device which is a ring of coloured areas and a ring of openings; a handle. The device is characterised by that the coloured areas correspond to symmetrical sectors of the ring which is concentric relative the handle. The sectors are formed on a plate which is joined to a support structure at a positioning point on the handle. The colour of the coloured areas and the colour of the plate are in contrast to each other. The visual display device has ring of openings formed on the handle. The openings interact with the coloured areas by turning the handle, which is suitable for changing the open/closed state of the rotating interrupter. The openings are formed on a circular screen which is monolithically joined to the hand, and correspond to the coloured areas. The circular screen has an outline part formed symmetrically about the indicator of the handle.

EFFECT: clear indication of the open/closed state of the rotating interrupter by rotating the handle.
