A module for transmission of a force including two toothed wheels which are connected to a main shaft; a first ratchet holder and a second ratchet holder which are provided with a first ratchet and a second ratchet, and are designed such, when they are actuated, to rotate the toothed wheels by support of the ratchet concerned against a tooth of the toothed wheel; a first cam and a second cam, which are designed to actuate respectively the first ratchet according to a first angular course around an axis YY' of the first cam, and the second ratchet according to a second angular course around the axis YY&#x2032; of the second cam, which is different from the first angular course.

The invention relates to an electrical switch device comprising contacts which are mobile through actuation of a first rotation shaft () and a control mechanism () for the mobile contacts which is situated in a housing and which can be rearmed via a second rotation shaft (). The first rotation shaft () passes through a first wall () of the housing and the device comprises a first rotation sensor () coupled with the first rotation shaft () outside of the housing, so as to measure the angular displacement of the first rotation shaft. The second rotation shaft () passes through a second wall () of the housing and the device comprises a rearming module () removably fixed outside of the housing against the second wall (), so as to be coupled with the second rotation shaft () to be able to rearm the control mechanism.

A drive mechanism of a circuit breaker comprises a master mechanism and a slave mechanism. The master mechanism is composed of an energy storage sub-assembly comprising an energy storage spring driven by a loading shaft, and an opening and closing sub-assembly driving a switching shaft. The master mechanism is controlled by a closing latch and an opening latch. The slave mechanism comprises a closing assistance spring connected to the loading shaft by means of a loading cam and a multifunctional lever. Rotation of the loading shaft loads the assistance spring and commands relaxation thereof. The assistance spring drives the switching shaft by means of an arm operating in conjunction with a crank in the form of a hook. At the end of closing travel, the arm uncouples from the crank and withdraws so as not to hamper opening of the mechanism. The assistance mechanism enables the energy delivered globally by the drive mechanism to be increased.

A multipole electrical switchgear apparatus comprises a drive mechanism equipped with a pole shaft and a plurality of breaking modules. Each module comprises a vacuum cartridge moved by a movable rod articulated on a transmission lever. The pole shaft is linked to the transmission levers by means of a connecting rod. This common connecting rod gives the kinematic transmission system a great strength. Furthermore, it enables switchgear apparatuses having variable distances between breaking modules to be produced inexpensively, based on a standard pole shaft. Finally, it enables differentiation of the switchgear apparatuses to be delayed.
