Low profile switch eg the veridian

I'm in the process off building a bike lite and I'm having problems finding good switches. I've been using DX's SKU 5604 which works okay, but I'd like something better and little different.
Such as:
Very low profile, pcb mount, single stage.

I recently found the verdian weapon lights, and really like the switch on it. Does anyone know if i can buy a switch like the one on that light OR how i could design it?
Thanks!

A little bump and some expansion. I found some switches that I think will work, they are "snap dome switches". The problem is the switch can only handle 50ma, so how do I connect it? Is there some sort of IC that acts like a relay that I can use?

I'm trying to make a really thin light using lipo battery with a custom pcb that has a micro usb charger and 3 amc7135 for driving the led, but I can't find and specific information on discrete components that drive these low amp switches.


Any tips would be great.

Thanks!
