Easy switch wiring question.

I have this switch here: http://www.radioshack.com/product.as...5Fid=275%2D701

It has no labeling on the back and I have no manual.. I'm using it to switch on / off some cooling fans..

How do wire it?

Thanks

You should just be able to break the Black (-) wire of the fan and connect the switch

<puzzled> Huh? </puzzled>

Can you be more specific please?

Thanks

So your saying I should run the power wires straight to the power source and then take the ground from the fans and put that to one peg of the switch and then the ground from the vehicle to the other peg of the switch?

All a switch does is break a wire, then when you switch it, it puts them back together. Get the fan running. Cut any of the wires in half. Put one end on one terminal of the switch. The other end on the other terminal of the switch. When its off the wires will be broken. When its on, it will put them together again. I suggest you buy one of those 50 in 1 science projects from radio shack that teaches you the basics of electronics. I had one when I was a kid and learned a ton.

Yes, That will work.... for fans (low current draw) it does not matter which wire is switched.

The switch opens (off) or closes (on) the circut for the switched part. I hope that helps.
