    Rotary switch?

    Has anyone had any success using a rotary switch on the back of a bike light? I'd like to use one for my on/off function. Or know perhaps where I could look for a good selection of switches online? I've been searching but it seems as though my search terms are too broad and not really getting me anywhere.

    I looked a while back but couldn't find anything small and waterproof.

    I think being totally waterproof is out of the question. Unlike a push button, It just doesn't seem mechanically possible. Or it's waterproof and it cost $25.

    small though. Small is important.

    You could make your own use a piece of tubing that will fit around the housing, assuming its round. Cut a hole in the under side.. silicone a small magnet in the hole and use a read switch fixed inside the housing..
    As you turn the piece of tube left and right it will activate the read switch(s)
    I have one of these light heads on my dive light.. the rotaing ring is the switch for off, 50% and 100% which uses the above method.

    Use one of these:


    Also check out this PDF for various other seals (pushbutton, etc).

    Goldigger- That's neat and I could see how it would work well for a dive light. For my aplication though I'm just looking for a small knob off the back of the light. Like a floor lamp. Perhaps I could use a pot as a switch instead of an actual switch.

    mtbikerTi- that's cool. So it's just the locknut with some rubber seals right?

    Yep, just a locknut with a seal.
