ABSTRACT:
A low-cost solenoid is provided for stopping an engine, which reduces the possibility of the occurrence of damage, generates little noise due to impact and is of a simple structure. The solenoid includes a suction coil and a holding coil both located within a solenoid body. Current to the suction coil is shut off by means of the movement of a plunger. The solenoid further includes an end wall provided at one end of the solenoid body, a pin which slidably extends through the end wall, a fixed contact provided adjacent the end wall and a leaf-spring shape movable contact configured to be in contact with the fixed contact in a non-operating position of said plunger. When the plunger is brought into an operating position, it contacts the above-mentioned pin to release the contact between the movable contact and the fixed contact.
