What is the function of a two-way switch in a circuit?

• A. A switch that directs current to one of two routes according to its position.
• B. A switch that opens and closes the circuit.
• C. A switch that increases voltage.
• D. A switch used only in series circuits.

Answer: (A)

A two-way switch is essentially a single-pole double-throw device. It has a common connection that can be linked to one of two outputs, so flipping the switch sends current along one path or the other. This routing is what the switch does—it selects which circuit branch becomes energized based on its position. It doesn’t create or boost voltage, and it isn’t limited to circuits in series; you can use it to control which branch a supply feeds in a variety of configurations. For example, you can switch between two different loads or between two parallel paths by moving the connection from one route to the other.
