Abstract
A device for controlling the switching of the contacts in an electrical apparatus comprises a unit inside, which are mounted a control lever in a pivot connection with the unit between two positions, a rotating element connected to the lever, and an actuating shaft connected between the rotating element and electrical contacts. The device further comprises a torsion spring mounted between the control lever and the rotating element, and a first and a second pawl scissor-mounted via a torsion spring, the first pawl cooperating with a first cam track of the lever to disengage the first pawl from a first stop and release the rotating element, and the second pawl cooperating with a second cam track of the lever to disengage the second pawl from a second stop and release the rotating element.
