Battery and switch to be mounted on vehicles
First Claim
1. An electromagnetic switch and battery comprising:
- a battery for mounting on a vehicle, said battery having a battery casing formed with a recess means therein for mounting said electromagnetic switch, said battery having two terminals;
said recess means being formed in an upper portion of the battery casing of said battery, between said two terminals of said battery;
a partition interposed between said electromagnetic switch and said two terminals, said partition being integral with said battery casing;
switch casing means for holding said electromagnetic switch, said switch casing means being formed with a first and a second end;
supporting means projecting from said first end of said switch casing means, said supporting means being electrically insulated from a negative terminal of said battery;
a magnetizable coil mounted in said switch casing means;
plunger means slidably fitted in said magnetizable coil;
moving contact means movable with a sliding movement of said plunger means such that said magnetizable coil is magnetized to attract said plunger means when a starter switch is turned on after a main power source circuit of a vehicle has been turned on by a key switch; and
first and second fixed contact members, said first fixed contact member connected electrically with said battery, said first fixed contact member having a first connecting terminal at a first end thereof which acts as a supporting member projecting to the outside of the second end of said switch casing means, said first connecting terminal being directly connected electrically and mechanically to the positive terminal of said battery, said first fixed contact member also having a second connecting terminal at a middle portion thereof, said second connecting terminal branching from said middle portion and being connected electrically with a load circuit of said vehicle, said first fixed contact member having a fixed contact at a second end thereof, and wherein said second fixed contact member is connected electrically with a starter motor circuit and is equipped at one end thereof with a third connecting terminal projecting to the outside of said switch casing means and connecting electrically with said starter motor circuit, and a second end of said second fixed contact member has a fixed contact wherein said fixed contact of said second fixed contact member and said fixed contact at said second end of said first contact member are rendered electrically conductive to start a starter motor by said movable contact member which moves in response to movement of said plunger means.

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. The rocking means is arranged such that the portion fastened to the positive terminal of the battery and the portion to be attracted by the solenoids are offset while holding a generally parallel relationship not in a common plane.
