this will show you how to do a homemade ON/OFF switch with stuff ou can find around the house from little to no cost to you

Step 1: Get All the Materials Needed

Give a general description of the Stepok so this will be very cheap...

- 2 paper fastners
- 1 paperclip (preferably small)

- 1 sheet of paper (not too big,all you need is 3 cm x 1 cm) -> you can get something harder,like cardboard so the switch doesn't break like mine did the first time

- a battery (i used a 9v because that was easier for me.you can use a 3v cell battery,whatever)

Step 2: Get All the Tool[s] Needed

so all you need is an xacto knife or some scissors...

Step 3: The Board

cut out a piece of paper ~3cm x 1cm

Step 4: Make Some Holes

make some holes (2) big enough for your thumbtacks or something

Step 5: The 2 Pins

put the thumbtacks as i did in the pic (or try to)

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
