A starter contactor for a heat engine, including a coil, in a bore of which there slides a magnetic core (,) of the type in which an external return spring (,) is in axial abutment against an external flange (,) attached to the core (,), of the type in which an internal bore (,) of the core (,) is open at its rear end (,) so as to define a rear shoulder surface (,) for abutment of an internal return spring (,) for a coupling rod (,) of a lever for actuating an actuator pinion, which rod (,) passes through the rear end (,) of the core (,), and is able to bear on a front base (,) of the bore (,) so as to be displaced by the core (,), characterised in that the front base (,) is integral with the core (,), and in that a capping piece (,) attached to the rear end (,) includes the rear shoulder surface (,) of the bore (,) and the external flange (,).

Starting switch with mobile core comprising a directly mounted closure cup

A contactor for a motor vehicle starter, of the type that includes a movable magnetic core which is displaced axially under the effect of a magnetic field produced by a coil, and of the type that includes a fixed magnetic core (,) which extends transversely to a front axial end of the coil, of the type in which the fixed core (,) includes a rear base portion (,) which is received axially in the coil and which has an axial through hole (,) to enable a movable contact finger to pass through, and of the type in which the fixed core (,) includes an annular front disc (,) which is assembled to the rear base portion (,), and which is mounted in a cylindrical seating of the contactor, characterised in that the front disc (,) consists of a stack of laminations (,).

Starting switch comprising a fixed magnetic core in several parts

In a motor vehicle starter contactor, a control plunger controls the axial displacements of a contact plate which is arranged in a front cover of the contactor. A fixed transverse core is arranged axially in front of the contactor winding, and an electronic circuit is fitted inside the cover, between the fixed core and a partition which divides the interior of the cover into two compartments. The partition, in the form of a separating plate, has a transverse wall portion and an axial bush in which the plunger slides. The bush has a central bore which is open at the front forwardly of the transverse wall portion, and open at the rear behind the fixed core.
