What type of switch will provide three-point control for a light?

To achieve three-point control for a light, the most effective setup involves using two 3-way switches and one 4-way switch.

In electrical wiring, a 3-way switch allows control of a light fixture from two different locations, making it ideal for hallways or large rooms where multiple entry and exit points are present. When you integrate a 4-way switch into this arrangement, it enables control from three or more locations. The 4-way switch fits between the two 3-way switches and can change the transmission path of electricity, thus allowing the light to be controlled from multiple points, specifically three in this case.

By using two 3-way switches that provide the initial control points and a single 4-way switch that connects the two, you create a functional circuit allowing the light to be turned on or off from three separate locations. This makes the combination the required answer for achieving three-point control.
