ABSTRACT:
A theft prevention switch device for use in a vehicle with an electrical system selectively operable off one of a plurality of battery sources. In the preferred embodiment, three electrical conducting means are attached to a support plate which can be mounted within a box that can be locked shut. One of the electrical means is connected to the vehicle's electrical system and each of the other two is connected to a battery source. The electrical conducting means are spaced from each other about a common point. A portable and removable plunger can be selectively placed to electrically connect the first electrical conducting means either to the second or the third electrical conducting means. The portable and removable plunger has two substantially planar portions joined at an angle and an insulated, cylindrical gripping member. The first electrical conducting means is spaced from each of the other two about a common common point at an angle corresponding to the angle between the planar portion of the plunger. The electrical system of the vehicle can be easily and quickly connected to either battery source by merely reversing the planar portion of the plunger received in the first electrical conducting means. The other planar portion of the plunger will then automatically be in alignment with either the second or third electrical conducting means.
