Patent ID: 8416551

Claim:
A starter for a thermal engine, comprising: a double contact electromagnetic contactor ( 10 ) comprising a solenoid actuator including a movable plunger core ( 100 ) and a pull-in winding, an electrically controllable micro-actuator including a micro-solenoid (MS) having a movable core (NM) and an electrical coil (BO), and an electronic control device (ECC); said electronic control device (ECC) comprising first transistor commutation means (T 1 , T 2 , CZ 2 , RC 1 , RC 3 , SL) to control the excitation of said pull-in winding (L a ) of said solenoid actuator of said contactor and second transistor commutation means (T 3 , CZ 1 , RC 2 ) to control the excitation of said electrical coil (BO) of said micro-solenoid (MS) of said micro-actuator.
