Abstract: One feature of the present invention is a battery to be mounted on a vehicle, in which the battery casing is formed with a recess into which a starter magnetic switch is fitted. Another feature of the invention is a starter magnetic switch which can be fitted into the recess formed in the battery. The starter magnetic switch has a rocker means which is made of a conductive material. The rocker means has a moving electric contact which is biased normally open and which is closed when the solenoids built into the switch are energized, to close the drive circuit of a starter motor. The rocking means has one end projecting to the outside of a switch casing and is fastened to the positive terminal of the battery. In addition, a supporting means, which projects to the outside of the switch casing at the side opposed to the portion where the rocking means projects, is fastened to the negative terminal of the battery.

Abstract: A fuse circuit unit for combination with an electromagnetic switch has a first terminal having one end thereof adapted to be connected to one terminal of a main fuse of a load circuit, and another end adapted to be connected to of the input terminal of the electromagnetic switch. The fuse circuit unti also has a second terminal having one end thereof adapted to be connected to another terminal of the main fuse, and another end adapted to be connected to the load circuit, and a casing supporting the first and second terminals. The casing of the fuse circuit unit is engageable with the electromagnetic switch, and the first terminal of the fuse circuit unit is removably fastened to the input terminal of the electromagnetic switch to mechanically and electrically connect them together. The casing is molded from a resin in a one-piece body, together with the first and second terminals.
