Making a switch from a paper clip wire stud 1) Push two metal fasteners through a piece of card. 2) Wrap a wire around the back of each metal fastener. 3) Slide a paper clip under one of the fasteners, on the top side. 4) If you move the paper clip round so it touches the other fastener, it completes the circuit.

Making a switch from two metal fasteners wire stud wire 1) Fold the card across the middle. 2) Push two metal fasteners through the card, one each side of the fold. 3) Wrap a wire around the back of each metal fastener. 4) If you fold the card so the two studs touch, it completes the circuit.

Making a switch from metal foil Foil (on other side) wire foil wire 1) Fold the card across the middle. 2) Using sticky tape over the plastic coating, attach the wires to different ends on the same side of the card. 3) Carefully stick on the pieces of foil, using sticky tape over the ends only. The foil must cover the exposed wires. 4) If you fold the card so the two pieces of foil touch, it completes the circuit.
