Claim 1
Independent Claim
190 words
In a breaker switch mountable on an automative vehicle, the combination of a base block of insulation meterial, mounting openings for said block at each end of said block, a pair of spaced apart terminals mounted upon said block, each terminal consisting of a flat copper plate secured to said block at one end by a small bolt and at its other end by a large bolt, said large bolt being fitted with a pair of nuts, each said plate having an upstanding leaf spring jaw contact adapted to retain removably a flat copper bar, one said terminal having a cable from a battery of said vehicle connected thereto between said nuts, so to comprise a positive terminal, and the other said terminal has a ground cable to a frame of said vehicle and a ground cable to a motor of said vehicle secured between said nuts so to comprise a negative terminal and said flat copper bar removably mounted in said leaf spring jaw contacts to close and open a circuit between said terminals, wherein all of said openings, bolts and contacts are aligned on the block center line.
