Make a switch
- What kinds of stuff do we have here that you could use to make your own switch?
- What kind of action would you want to take to turn your switch ON or OFF?
- What ideas do you have for making your switch?
Help students see that a switch needs to have two places, metal contacts where it connects to a circuit. The switch also has a conductor that can be moved to touch the two contacts and allow current to flow between them. The switch is then ON, and the circuit is closed. This conductor can also be moved so it doesn’t touch both contacts. Then there is no way for the current to flow from one contact to the other, the switch is OFF, and the circuit is open. No current will flow in the circuit.
