Switches now allow students to break a circuit at will. By connecting the paper clip (pictured below left) to each brad on the index card, students can turn on a light bulb. Swing the paper clip away from the opposite brad, and the light goes off. The back of the switch (pictured below right) shows the Fahnestock clips where the wires are connected and kept out of sight. This should come in handy in the next lesson - making their own flashlights using the knowledge they have gained.
