Binder Clip Switch

This one is pretty simple. The binder clip switch operates just like the light switches in our walls. These types of switches are called toggle switches. They stay on or off until the switch is flipped.

Parts Needed:

• cardboard
• 2 small binder clips

Steps:

1. Clip two binder clips to opposite sides of a brick.
2. Flip one arm flat against the brick. If it touches the other binder clip, cut a larger brick.
3. Leave one arm down.
4. When you flip the opposite arm down, it completes the circuit (turns on). When you lift the arm it turns the circuit off.
5. Label with “Binder Clip Switch.”
