This diagram above by http://www.teachengineering.org shows a flashlight circuit.
The switch is open, electrons cannot flow, the light is off.
The key to understanding complex switch wiring is to learn how to identify or visualize the conducting path.
Single pole switches are used when only one switch is needed to control one or more lights.
They are the only switch labeled "ON" and "OFF" and the only switch with two terminal screws
(with a third green ground screw). They are identified on blueprints as S1.
The methods that follow are explained with
1) Line diagrams 2) Wiring schematics and 3) Photos .
Line diagrams help electricians figure out how to make wiring connections by simplifying the circuit.
Line diagrams are drawn with the hot on the left and the neutral on the right.
Wiring schematics are more like a drawing of the real thing, like a road map.
To keep the illustrations simple, the grounds are not shown. Green or bare wire grounds are connected together and to any metal parts in the circuit that are not supposed to be electrified, parts like a metal box (instead of the blue plastic box used here) and the metal canopy of a light fixture (instead of the white plastic light used here) and the metal yoke of the switch that has the green ground screw.
