what is the switch on a ceiling fan for

The switch on a ceiling fan usually changes the direction the blades spin. That lets you use the fan differently in summer and winter: one direction creates a cooling breeze, and the other helps circulate warm air near the ceiling.

Quick scoop

• Summer: set it so the fan blows air downward for a cooling effect.

• Winter: reverse it so the fan gently pushes warm air back down into the room.

• On some fans, the switch may also be part of the fan/light control or a speed control , depending on the model.

If you want, I can also tell you which switch position is usually summer vs. winter.
