ABSTRACT:
A starter of an engine which comprises a starting motor, a detector which generates a voltage corresponding with a revolution of the engine, an electromagnetic switch having a coil which draws a plunger that supports a moving contact so that fixed contacts are shorted by the moving contact, and a magnet which retains the drawn plunger, a main switch and a usually open touch switch for activating the electromagnetic switch in starting up of the engine, a voltage comparator which compares a weak inverse direction current flown in the coil when the fixed contacts are closed, with the voltage from the detecting means and outputs a current when the voltage is higher than the weak inverse direction current, and a switch device for stopping the starting motor which makes ON and OFF according an output from the voltage comparator and generates an inverse drawing force by flowing a strong inverse direction current in the coil.
