Which of the following is a type of switch designed to control a circuit from two locations?

• A. Push
• B. Push-to-Break
• C. Two-Way
• D. Relay

Answer: (C)

Two-way switches are built for control from two locations. In a typical two-location setup, two switches are wired with traveler wires so either switch can connect the circuit to the load, turning it on or off from either spot. This is why you’ll see lights that can be turned on from the top and bottom of stairs: flipping either switch changes which path is connected, regardless of the other switch’s position. The other options don’t provide this multi-location control: a push switch is a momentary contact that only stays active while pressed; a push-to-break switch opens the circuit only while pressed; a relay is an electrically operated switch controlled by a coil, not a manual two-location control.
