Abstract: A contact-breaker for a heat engine starter comprises a cap, a micro-solenoid having a coil which is stationary relative to the cap, and a core which is translational relative to the cap between a starting position and an end position. At least two contact terminals are stationary relative to the cap. A contact plate is inside the cap and is movable between a deactivated position in which the contact plate is spaced from the contact terminals and an active position in which the contact plate is in contact with the contact terminals. The contact-breaker is characterized in that the contact plate is secured to the core of the micro-solenoid in such a way that the contact plate drives the core of the micro-solenoid towards the starting position of the core when the contact plate moves from the active position into the deactivated position.

Abstract: A starter comprises an electric motor which drives a rotor shaft, a drive shaft that can be rotationally coupled to the rotor shaft, and a pinion mounted on the drive shaft and movable in a translational movement between a rest position and an active position by a movement system. The starter comprises a coupling system that couples a rotary movement in one direction of rotation of the rotor shaft to the pinion. The coupling system moves from an uncoupled state into a coupled state and vice versa. In the coupled state, the rotor shaft is firmly attached to the pinion in the starting direction of rotation. In the uncoupled state, the pinion is disconnected from the rotor shaft in both directions of rotation. The starter further comprises a movement system for moving the pinion from the coupling system into the uncoupled state as it moves the pinion into active position.
