Electromagnetic switch for the starter of a heat engine, comprising at least two movable contacts

摘要

An electromagnetic switch for the starter of a heat engine, including a first terminal (B1), a second terminal (B2), a first mobile contact (C1) which is movable between an inactive position and a power supply position, and at least one second mobile contact (C2), which is placed between the first mobile contact (C1) and the second terminal (B2) and which is movable between a disconnected position and a connected position. The switch is capable of being placed in three operating states: an inactive state, an engagement state, and a power supply state.

1. An electromagnetic switch for the starter of a heat engine, comprising:
a first terminal (B1); a second terminal (B2); a first movable contact (C1), which is located between said first and second terminals (B1, B2) and which is movable between a disconnected rest position and a connected power supply position; a core (P1), of a first coil (L1), designed to activate a system for operating a launcher (L) of said starter, controlling the displacement of said first movable contact (C1); a second movable contact (C2), which is located between said first movable contact (C1) and said second terminal (B2) and which can be moved, between a disconnected rest position and a connected position, by a core (P2) of a second coil (L2) and by a spring,said switch being capable of being placed, according to a power supply of the coils, in three operating states:
a rest state, wherein said first movable contact (C1) is electrically isolated from said two terminals (B1, B2), and in that said two terminals are isolated from each other; an engaged state, wherein: said first movable contact (C1) is in an engaged position between said power supply position and said rest position and is in electrical contact with said first electric terminal (B1); said second movable contact (C2) is in said rest position and is in electrical and mechanical contact with said first movable contact (C1); said second terminal (B2) is electrically isolated from said movable contacts and said first terminal (B1); a power supply state, wherein: said first movable contact (C1) is in said power supply position and is in electrical contact with said second terminal through said second movable contact (C2) and is in electrical contact with said first terminal (B1); and said second movable contact (C2) is in a connected position and is in electrical and mechanical contact with said second terminal (B2).
