| 摘要 |
The invention concerns a heat engine starting switch comprising a coil, in a bore wherein slides a magnetic core (32), of the type wherein an outer return spring (58) presses axially against a directly mounted external flange (56) of the core (32), and wherein an internal bore (36) of the core (32) emerges at its rear end (52) to form a rear shoulder surface (42) supporting an inner return spring (38) of a link rod of a lever actuating a driving pinion, which rod (26) passes through the rear end (52) of the core (32), and is capable of pressing against a front base (48) of the bore (36) to be driven by the core (32). The invention is characterised in that the front base (48) is made in one piece with the core (36), and a cup (54) directly mounted at the rear end (52) comprises the rear shoulder surface (42) of the bore (36) and the external flange (56).
