How do two switches control one light?
Two separate light switches are able to control a single light through the use of special electrical wiring and a three-way switch. A three-way switch connects the two switches and the light together, creating an uninterrupted, but controllable, circuit amongst all components.
What is the standard light switch?
The simplest and most common light switch is actually referred to by hardware dealers and electricians as a “single-pole light switch.” With a single-pole light switch, flipping the lever up completes the circuit, turning lights or appliances on, and flipping it down breaks the circuit, turning lights or receptacles off.
