Abstract
The starter electromagnetic switch includes a switch coil creating magnetic force to move a plunger for closing the main contact thereof, a switch terminal bolt having a head portion fixed to a switch cover covering the main contact, and a shaft portion to which a switch cable is fastened by tightening a nut thereto, and a conducting plate for electrically connecting the switch coil and the switch terminal bolt to each other. The conducting plate has a mounting hole formed therein. The shaft portion is passed through the mounting hole without making contact with the conducting plate. The conducting plate is supported by the switch cover in a state where a certain distance is kept with a bearing surface of the switch terminal bolt when the nut is not tightened to the shaft portion.

A starter electromagnetic switch having a main contact through which electric poser is supplied to a motor starter of a vehicle engine, said electromagnetic switch comprising:
- a switch coil creating a magnetic force to move a plunger slidably disposed in said switch coil for closing said main contact when a current is supplied to said switch coil;
- a switch terminal bolt having a head portion fixed to a switch cover made of insulating material and covering said main contact, and a shaft portion to which a vehicle side switch cable is fastened by tightening a nut to said shaft portion;
- and
- a conducting plate located outside said switch cover for electrically connecting said switch coil and said switch terminal bolt to each other;
- wherein said conducting plate has a mounting hole formed in one end side thereof, said shaft portion being passed through said mounting hole without making contact with said conducting plate, said conducting plate being supported by said switch cover in a state where a certain distance is kept between said one end side of said conducting plate and a bearing surface of said switch terminal bolt when said nut is not tightened to said shaft portion of said switch terminal bolt.
