Understanding Your Circuit:
LilyPad Slide Switch
The LilyPad Slide Switch
has a small switch labeled ON/
OFF. When the toggle is moved
to the ON position, the two
sew tabs on the switch are
connected, allowing current
to flow through and close the
circuit. When moved to OFF,
parts inside the switch move
away from each other and open the circuit (disconnecting it). It helps to
visualize switches as drawbridges for electricity – when the bridge is up
(open), nothing can cross over. When it is down (closed), the pathway is
reconnected, and electricity can flow along the original path.
