    Bump proof switch?

    I need to install a switch in the trunk of my car. The electrical specs are nothing special - DPDT 3 or 5 A at 12VDC. The problem is that it needs to be "bump proof" - it has to stay the way it set no matter what moves around in the trunk and hits it. Ditto for any car motions, not just normal vibrations, but even a smallish collision. (A big one and it won't matter.) It is going to be "panel" mounted in the plastic trunk linker, so it should not stick out too far.

    So far I have not found a solution that I like. There are toggle switches with flip up covers, like this:

    but I don't much like the look and they are really designed for cockpits, and control panels, not trunks.

    Perfect would be something where there is a locking screw, for instance, that had to be loosened before the switch could move. (Tools are OK because the switch only changes position when the car is being serviced in a certain way.)

    I thought about using a regular rocker switch, and then custom making a cover that screws down over it. That will work, but somebody, somewhere must sell something like this already.

    Any ideas?

    rotary switch is the answer.

    there used to be special toggle switches that you had to lift/pull to move but those are very rare outside of the military suppliers.

      Here are a couple dpdt switch with cover or you can just get the cover, or there are ones that you need a key to operate

        the toggle switch is no good,
        the cover only fits down in one direction intentionally.
        hard to turn on, fast to turn off!

          Missed that he did'nt want that type of toggle. There are those slide switches used on some power supplies for changing input voltage, you need screwdriver to slide them, they look something like this

                  These I think (see page 9 of the PDF)

                  The sliding voltage range switches are looking pretty good.

                  Thanks.

                      How about one of these?

                      keep the key next to your ignition key and you won't be without it.
