A dimmer switch controls light output level, not power or protection.


It is still a switch.





What It Does



A dimmer regulates the amount of power delivered to a lighting load to adjust brightness.





Where It’s Used



  • Living spaces

  • Bedrooms

  • Areas where light level control is desired






One Critical Rule



A dimmer must match the load type.

Using a dimmer on a motor or incompatible LED causes noise, flicker, and failure.
