Battery shut-off switch

If you are "tricky" you can turn that into an "anti theft" device on a street car. According to NHRA, the switch must PUSH off, so here's what you do: Either take the supplied rod, or get something else for the rod, and some tubing, brake tubing, etc, that is a "slide fit." With a collar on one or t' other to keep the knob / outer part captive, you can push it off, but all pulling would do is to "slide" the tubing on the rod.
