This is Matthew and I am going to show you how to make a switch.

First fold the index card and punch a hole at one end of the index card.

Put the paper fastener through one end of the paper clip and then through the hole. Fasten the paper clip to the index card.

Punch a hole through the index card close enough for the paper clip to touch. Put the other paper fastener through this hole and fasten to the index card.

Tape the ends of the paper fasteners under the index card so they do not touch each others.

Connect the wires as shown,winding them around the paper fasteners once or twice.

Close the switch by pressing the paper clip on the paper fastener.

Then you are done
