I contacted Tiablo on this a couple of weeks ago and they said that they would be coming out with a tape switch for the A8 shortly. So, if you can wait a bit...
 
As the DIY Wolfhound posted suggests, a cheap 123A powered laser is one way to go and for less than US$15 shipped too. You could then plumb a clicky into the wire stub and have a nice laser toy with mount also.

Already did this - 1st line of enquiry but no time scale.

I also want to mod a couple of other units so it will be useful to pop my DIY cherry and dip a toe into the water. Not looking forward to it though. I can burn water
 
A warning about using cheap laser tape switches especially with high current lights: the switches may not be designed to carry a large current, and could overheat or even melt with a very powerful light...
 
If you're willing to scavenge from a new switch, G&P makes a cheap one. I have no info about reliability, but it seems to sell well to the airsoft folks (maybe because it's cheap?).

Cruising the clearance pages at Lighthound, he's got a generic green laser one for $8:

and a G&P for $15. That's as cheap as eBay without the $9.99 shipping the Hong Kong sellers all seem to charge.


Being cheap comes in handy :broke:
 
Another option is a spring switch. I made one for my Snake Eyes II light, and it works marvelously. Plus, it can carry tolerable current if needed (assuming proper component selection) although it's actually a momentary switch design.

Here's what mine looked like:

Such a switch works from any angle, and can be made waterproof by encapsulating it inside a sealed flexible tube. It can be sensitive to false activation, however, if the spring is not stiff enough and/or the open center area between spring supports is wide enough.

Just a thought... 😀
