ABSTRACT:
A key-operated electrical switch assembly is provided and is designed primarily to be used in conjunction with the electrical system of an automobile or truck as a means to provide a source of electric power. This assembly was devised primarily for use with alternator powered electrical systems, as are now utilized in most automotive vehicles. Furthermore, it is designed and constructed in such a manner that the assembly could not be left in an "on" position if one desired to retain the security of the key. This switch assembly includes an insulated plastic enclosed structural support frame, consisting of a rectangular base upon which the switch is mounted, the switch assembly, which is made operative by a coupling means effectuated by a longitudinal actuating plate and controlled by a perpendicular projecting pin which transverses rectilinearly along a longitudinal tract located above the actuating plate, said tract containing a lock bolt attached to the projecting pin; and a key-operated lock device which controls the rectilinear movement of the lock bolt. A universal mounting bracket and a switch cover are also components of the switch assembly. This invention is capable of providing for a minimum power output of at least 20 amperes.
