Default Is there a key-lock switch for this host?

Title says it all, I want to be able to lock my laser with a key and turn it on only when it is unlocked.

I know those cheap green lasers from china come with them in the back so here is the host:

Here is the china one

Hi Avatar,
Not for the SL at the time , if they did you would need a side button host.

A couple of higher quality alternative sources for the key-lock switch style are either Jetlasers, or Laserbtb, they both have what you are looking for.

Default Re: Is there a key-lock switch for this host?

Not sure is the is the best thread to post this on (as opposed to starting a new one) but ...

Do you all think that a tumbler based key is really that much better than a dongle based key for laser safety? It seems that dongles can be cheaper and take up less space in the host that a tumbler based key.

A simple resistor based dongle could connect points A and B with a 4K resister and points A and C with a 7K resister. The laser would just have to the electronics in a circuit that tests the resistance between the points and allows for some tolerance.

I can't see why the dongle would be less safe, sure an unauthorized person can build a duplicate dongle, but defeating an electronic tumbler switch is pretty easy too. The idea with the key is to, prevent a child or someone who doesn't know he/she is dealing with a dangerous object from turning on the beam..

This is the mini barrel key switch like the one JetLasers uses--perhaps you can or you can find someone who can adapt it to the tailcap or body whatever host you decide to use.
