It seems most of the headlamps these days have electronic push button on/off switches. Which makes sense, since these often have multiple functions depending on how long you push on them. In theory, the PB switch should have better long term reliability than a slide switch and easier to make waterproof or resistant.

There is only one problem - they keep coming on in my pack and running the batteries down! Sometimes I notice, often I don't. It's frustrating to find the light really dim or worse, dead.

Sure, I could take out one of the batteries to keep that from happening, but then I got a loose battery to keep track of and have to remember to put it back in when I need the light. If you have one of those high end rechargeable headlamps, that's not an option.

I'm thinking the only solution is to store the headlamp in some non-crushable container. A small plastic jar or something. Got to start looking for a suitable container before fall gets here and I really need a light!
