Patent ID: 8664549

Claim:
A switchgear device comprising: a single-pole main switching unit supporting an operating mechanism, and a first single-pole auxiliary switching unit, said units being arranged side-by-side in a transverse direction and each, respectively, comprising: a rotary bar mounted in a mobile contact bridge for rotation around an axis of rotation; which extends in said transverse direction; a pair of stationary contacts of said mobile contact bridge, each of said stationary contacts being connected to a current input conductor, the operating mechanism of the switching units comprising a handle for moving a drive rod that passes through the rotary bars, whereby an angular movement of the entire length of said drive rod drives the rotary bar of the mobile contact bridge between an open position and a closed position of the contacts, and compensation means comprising a stop against which the drive rod presses in the closed position for: locally limiting movement of the drive rod at a level of the first auxiliary unit, and applying a rotational torque to the drive rod to keep it parallel to said axis of rotation.
