Led laser switch thing

A friend is wanting to make little led lasers from a button cell and and led. However they want to make it able to be switched on and off by squeezing it. Looking for something DIY here, so that people can get involved Smile

Solder two pins of a tactile button switch to the battery, the other pins to the LED and the last LED leg to the other side of the battery. Use a toggle style tactile switch and you can make on/off LED throwies Razz

not sure if there will be soldering irons available, but I guess tape would work in the same manner

If soldering equipment isn't available, try using magnifying glasses in bright sunlight, should be able to get enough temp to melt solder Smile

this is 6pm in a club Razz, and I refuse to put batteries under a magnifying glass... have you seen mine? It's for a 17" monitor and focuses sunlight down to about an inch... we couldn't see after that, I will have to see how small a spot I gan get when wearing my welding helmut

a jet lighter and fast hands works just as well as a soldering iron Laughing
