The answer to 'types of dimmer switch' is there are several main types of dimmer switches for homeowners to choose from. The most common are slide dimmers, rotary dimmers, and smart/digital dimmers. Slide dimmers use a sliding lever to control the light level, rotary dimmers have a turning knob, and smart dimmers connect to your home's WiFi for remote control and automation.
Each type of dimmer has its own advantages. Slide dimmers are simple and intuitive to use, while rotary dimmers provide a more precise level of control. Smart dimmers offer the most flexibility, allowing you to adjust lights from your smartphone or integrate them with a smart home system. The right dimmer for your needs will depend on your home's electrical setup, your lighting needs, and your personal preferences.
