Step 6: The thing that connects the 2 pins together

ok so now place the paperclip as i did in pic (open it a little bit and then close it)

Step 7: Test it!

in the 1st pic,the paperclip touched only 1 thumbtack which touched the LED
the other thumbtack touched a metal bar which was connected to the battery

because the paperclip touched only 1 thumbtack ,it wouln'd allow the electricity to traver trough it to the LED

in the 2nd pic,the paperclip touched both thumbtacks which allowed the electricity to traver trough it and get to the LED

Step 8: Finished

Picture of finished
well you are finished

enjoy your homemade ON/OFF switch!

Will this work in a large circuit (five switches, one led)?

what did you use to test the switch.. I mean the wires connected to the battery. Is that just a flattened out paper clip?

Did this for a speaker with push pins, a paperclip, a piece of cardboard and a little bit of solder, worked like a charm. Thanks! :)

This is a really nice switch. It is simple, but effective. I have a litte motor, now I can install it on a car or something. Thanx.
i cant tell how the paperclip goes and i those arent thumbtacks but this is a great idea

-i know the're not thumbtacks,i didn't know the name of it so i put something that looks like it -you open the side a little bit,put it under the large part of the (thumbtack?) and you close it so it doesn't come off -i will also put a pic or 2 on how the paperclip goes on it so you can understand -check my other instructable,ask questions if you need,and rate it thanks - Alex

Needless to say (I hope) don't try this with mains voltage ;¬)

I know I shouln'd but the 9v battery was easier because both the ends were in front so I didn't have to use a battery holder or something rate my Instructable please? thanks - Alex
