Planning, installing and troubleshooting circuits using electrical dimmer switches for controlling the brightness of lighting.

Dimmer switches are electrical devices used to control the power in an electrical circuit, typically used to dim or brighten lighting. Early dimmers used variable resistors to do this, but that causes a lot of heat dissipation within the switch. Modern dimmers use solid state electronics and are a lot more energy-efficient. Recent improvements to the technology allow LED and CFL bulbs to be dimmed effectively.
