<p>A rope-operated bistable commutation device, comprises a box-like body (2) for housing at least one switch (3) connectable to a corresponding electric circuit, a bistable commutation unit (4) operably associated to the switch (3) to promote commutation thereof between a closed circuit condition and an open circuit condition, wherein the unit (4) comprises an actuator (5) designed to be associated with an actuating rope (F) and guide means (6) for guiding the actuator (5) between a first stable operative position (A) and a second stable operative position (B) corresponding to open and closed switch (3) conditions respectively. The unit (4) is removably connected to the box-like body (2), locking means (7) being provided for holding it constantly joined with the actuator (5) set in either the first (A) or the second (B) stable operating position to allow one-piece removal thereof from the box-like body (2).</p> |
