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.

Starter contactor comprising a sealing device and starter comprising such a contactor

The invention relates to an electromagnetic contactor including: &#x2014;first and second magnetic cores, the second core being mobile relative to the first core; &#x2014;a control rod mobile between an inoperative position and a supply position, the control rod comprising a shoulder, in inoperative position: &#x2014;the shoulder comprises one surface in contact with the first magnetic core, &#x2014;the first magnetic core and the control rod separating a first chamber extending between the first and second magnetic cores and a second chamber in which the contact plate is located, and &#x2014;at least one opening made between the first chamber and the second chamber allowing the transfer of air from the first chamber to the second chamber when the second magnetic core moves from the inoperative position to the magnetized position.

Electromagnetic power contactor provided with control rod having stop

A contact device () of a starter contactor () comprising:&#x2014;a contact rod () made of an electrically insulating material,&#x2014;a contact strip () made of an electrically conducting material comprising a hole () in which is mounted the contact rod (),&#x2014;a squashing spring (),&#x2014;a restoring spring (), the contact device () also comprises a closure clip () of radial width greater than or equal to the diameter of the squashing spring (), a radial notch () being made in the closure clip (), the radial notch () receiving a portion of the contact rod (), the squashing spring () being mounted compressed between the closure clip () and the contact strip () which is in abutment on a retaining collar () of the contact rod ().
