Normally Open (NO) and Normally Closed (NC) mean just what they say. When the slide switch is moved to the NO (Normally Open) position, pressing down on the lever arm closes the circuit. In the NC (Normally Closed) position, the circuit will be closed until you press down the lever arm to open it.

The NO/NC Switch is just one part of a circuit. Add a battery to power your creations, a motor to make them move, an LED to light them up, and a switch to take control!
