A starter switch () comprises a housing () extending along an axis (X) that delimits at least one interior space (), at least one coil () housed in said interior space (), at least one fixed core () passed through by a shaft () that is movable in translation along the direction of the axis (X) and at least one cavity () comprising an electrical connection area, said cavity being separated from the interior space () by the fixed core (). The starter () switch () comprises at least one sealing device () providing a seal between the interior space () of the starter () switch () and the cavity () comprising the connection area.

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.

Micro-solenoid contactor for motor vehicle starter, and corresponding starter

The invention essentially relates to a contact-breaker () for a heat engine starter, comprising: &#x2014;a cap (); and &#x2014;a micro-solenoid () that comprises a coil () which is stationary relative to the cap (), and a core () which is translationally movable relative to the cap () between a starting position and an end position. The contact-breaker () comprises a means () for retaining the core () of the micro-solenoid () in the end position.
