RF light switches vary, with many primary switches requiring a neutral wire while companion switches in multi-location setups may not. A neutral-required switch needs an available neutral connection in the wall box, while a companion switch can simplify installation where the neutral is connected at the primary control.

RF light switches use radio frequency communication to link a primary switch or dimmer with companion controls, allowing residential or commercial lighting to be operated from multiple locations without running traditional traveler wires between each control. Many systems support up to four companion switches or dimmers with one primary control, creating control from as many as five locations, with options for on and off switching or dimming.

RF light switches in this assortment support common lighting loads, including dimmable LED bulbs and fixtures, incandescent, halogen, electronic low-voltage (ELV), and magnetic low-voltage (MLV) loads, depending on the specific switch or dimmer. Certain on-off RF switches also support motor loads, with listed capacities of up to 8 amps for lighting and 5.5 amps or one-quarter horsepower for motors.

Wireless range and infrastructure depend on the RF lighting system: some switches should be installed within thirty feet of a repeater, while others require placement within seventy-five feet of a wireless processor. For systems using Clear Connect-Type X devices, plan for at least two other non-battery-powered devices within twenty-five feet of each RF switch or dimmer to support the wireless network.
