An optical traffic signal column including stacked levels fixed to one another by rotation. The base of each level includes, distributed along its periphery, oblong passages and fixed connectors. The conductors include rods each having two ends angularly offset from one another, and including a common conducting rod and a stage-specific conducting rod. The connector rods are identical and respectively fix the bottom of a conducting rod of the relevant level and the top of the respective conducting rod of an adjacent level, the angular offset between the two fixing points corresponding to that of ends of the conducting rods. The conducting rods are mutually arranged and mounted to effect, from one level to the next level, an essentially identical angular position of the common conducting rods and an angular offset of the stage-specific conducting rods.

Traffic signal column

An extended actuating device for a circuit breaker is provided, including a trip assistance device having a first rotary device integral in rotation with a control lever of the circuit breaker. A second rotary device is integral in rotation with a remote control device. The second rotary device is able to be driven in rotation by the first rotary device as far as a first position corresponding to the tripped position of the lever of the circuit breaker. A return spring is provided to force the second rotary device towards its first position. A breakable mechanical link device releases the return spring when its breakable mechanical link is broken.

Extended actuating device for a circuit breaker including a trip assistance device

The invention relates to an actuating device () for an electrical switch device comprising a body () upon which is mounted a hand lever () that rotates about a main axis (A), cooperating with a transmission shaft () able to control the opening or the closing of electrical contacts of the electrical switch device and elastic linking means between the hand lever () and the transmission shaft (). The device also comprises means () for locking the rotation of the hand lever () with respect to the body (), used when an angular divergence between the hand lever () and the transmission shaft () exceeds a specified threshold. The purpose of the invention is to limit the damage to the hand lever and to the electrical device when an operator attempts to return the hand lever () to its 'Off' position whilst the contacts are welded and to prevent the beginning of electrical arcing if the operator should succeed in unsticking the contacts when rotating the hand lever

Actuating device for an electrical switch device with rotational locking means

An actuation device of an electric switching device includes a body onto which is mounted a rotary control handle and a device for locking the rotation of the control handle making it possible to lock the control handle when the latter is in the 'Off' position. The locking device includes a locking member that can move in translation along a main axis, a sliding element mounted on the control handle, that can move in translation along the main axis, and that defines an opening that can receive one or more padlocks in a locked position. The locking device also includes an operating mechanism interacting, on the one hand, with a locking member and, on the other hand, with the sliding element to convert the translation movement of one in a predetermined direction into a translation movement of the other in an opposite direction.
