I was expecting that more people use keyswitches with there diy high power pointers. Just like gun safes, they seem mandatory.
Cheap insurence if you will.
But i see what you mean, if nobody uses one, nobody knows a good brand. I personally did already have keyswitches from "Eaton" and some chinese ones. The Eaton ones are good quality, nice firm turning action, nice satisfying click with tactile feedback. But to big for my project. The chinese ones do not click, the key fits poorly and wiggles around, turning feels like the switch has sand in it.
Thats what i mean, the chinese one does not fit the bill. Eaton would, if it wouldn't be for the size.
The fingerprint reader seems like a nice option, i looked into it. But i see a problem: the think would use power even if turned of, and i need a uC it interface with it. Seems like "over the top" but still, its for a 3,3W RGB handheld laser pointer, soooo would fit nicely
