Stabilization circuit of magnet switch for starter
First Claim
1. A stabilization circuit of a magnet switch for a starter, comprising:
- a motor unit 12 which starts an engine;
a pull-in coil(PL11) and holding coil(HL11) which are magnetized and generate a magnetic force line when a key switch(KSW11) is turned on;
a plunger 11 which is absorbed by a magnetic force line generated by the pull-in coil(PL11) and holding coil(HL11) and supplies a driving power to the motor unit 12 by connecting contact points (B11) and (C11) for thereby supplying a driving force to the motor unit 12 and prevents the pull-in coil(PL11) from being magnetized; and
a diode(D11) which prevents a power flown through the contact points(B11) and (C11) and the plunger 11 from being flown to the pull-in coil(PL11) and the holding coil(HL11) when the key switch(KSW11) is disconnected.

Abstract
The present invention relates to a stabilization circuit of a magnet switch for a starter in which an electronic switch of a starter which starts an engine installed in a vehicle is stable-operated. In the present invention, a current is prevented to flow to a pull-in coil and holding coil when disconnecting a key switch using a diode which is capable of flowing a current in a normal direction and preventing a flow of a current in a reverse direction, so that it is possible to accurately return a plunger to its original state. Therefore, the operation of a motor unit is stopped by opening two contact points. In the case that a key switch is turned on by connecting a diode between the contact points and the pull-in coil, the pull-in coil and holding coil are magnetized, and in the case that the key switch is turned off, the current is not flown to the pull-in coil and holding coil, so that the pull-in coil and holding coil are not magnetized.
