ACTIVITY MATERIALS

A switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit. Interrupting the electric current turns the LED off, connecting the current turns it on. 

THE SWITCH

An LED circuit requires three basic elements. The light, the wires that create a loop, and a battery. 

A switch can also be added to allow you to open and close the circuit, turning on and off the light.

BUILDING A SIMPLE CIRCUIT

Securing the wires to the switch

Attach the metal ends of wires through holes of switch prongs

Secure each side with tape - make sure the wires aren't touching each other!
