I need a switch for my Mini-Maglite LASER build

Hi Guys,

I’m trying to build a laser sight for a rifle.

I was going to use a Ultrafire 501b host because I wanted a momentary switch and be able to place it under my finger tips.

The negative issue was that their remote tail switch required a major amount of pressure to make contact, so I rejected that.

BTW, if anyone has opened one of these remote tail switches up and thinks the pressure needed to activate the switch can be modified, please speak up!

The Mini-Maglite host is a much easier fit.

I have the 30mW, 532nM laser module working in the Mini-Maglite host as we speak, with a Nite Ize tail switch, very easy build.

I’m still looking toward the Mini-Maglite remote tail switch. I’ve never seen or used one.

So my question. If anyone has used or preferable owns one now, would I be able to hold that switch on for up to a minute without problems? If the switch takes several pounds of force to operate, this switch isn’t my desired solution.

It wasn’t a initial design requirement, but this build is pretty much water proof and looks very durable.

I’ve still got to work out a mount that I like. I’m thinking about prototyping something that will mount on my picatinny rail. We’ll see.

Thanks for your time.

Be aware that most green lasers are made with an infra-red laser diode and a series of very delicate and very precisely aligned non-linear crystals that convert the IR to green light. Rifle recoil can easily kill the magic crystal foo…

Boy, I should have had “pyro” in my screen name…

Thanks for the heads up, it’s for an AR-15.

I’m here to learn, please feel free to PM me if you know more about weapons mounted lasers.

Thanks again!

There are true green laser diodes available, but they are expensive. And you might get sold a diode pumped solid state laser (crystal based) and not know it. Blue lasers are made, but they tend to be high power and very dangerous. Violet lasers from blue-ray players and plentiful and cheap, but not very visible.

Your best bet is probably a red diode laser, even though they eye is less sensitive to red. The shorter the wavelength, the more visible it will be. A 632 nm diode laser is a good bet. I don’t know how good these are, but they are inexpensive and already set up for use on a gun: http://www.ebay.com/itm/AimSHOT-KT6132-632nm-Compact-Laser-Sight-w-Rail-Mount-/200081993561?pt=LH_DefaultDomain_0&hash=item2e95d0ef59#ht_1060wt_802

I kind of thought the green pumped lasers were more frail than diode based ones.

My thing is that I want to build it myself, not buy someone else’ work. I want to be able to repair it when it fails.

Anyway this is the first build, I think perhaps of several. Kind of a proof of concept.

Just to be clear, I think you are saying that a straight diode based laser is more durable in this kind of application?

Thanks again man!
