device for cutting and cortocircuitamento bipolar for cables of supplies series, particularly for lighting, comprising a body scatolare transparentwith the fixed contacts, and a rotor movable contacts, treatment
The two-pole disconnecting and short-circuiting device for power supply cables of series circuits, particularly lighting circuits, comprises a box-shaped casing 6 which incorporates the fixed contacts 01, 01', 010, 010' which are enclosed within it, the moving contacts 2', 20', 4, 40, 4', 40' being placed on a single rotor 3 which is lockable, operable and observable from the exterior. Three distinct steps which can be monitored from the exterior can be executed in complete synchronization by a travel of 90 degrees and a single command 30.
