To control a load from four locations, the switches needed are

• A. Four three-way switches
• B. Two three-way and two four-way switches
• C. One three-way and three four-way switches
• D. Three four-way switches and one three-way switch

Answer: (B)

To control a load from multiple locations, you use 3-way switches at the ends and 4-way switches between them. A 3-way switch can direct power to one of two traveler wires, letting the load be controlled from either end. A 4-way switch sits between two 3-ways and swaps or passes those traveler wires, effectively adding another control point without providing a direct hot or load connection. For four locations, you place end points with 3-way switches and insert two 4-way switches between them, giving four control points in total. This combination—two 3-way switches and two 4-way switches—lets you operate the load from all four locations.
