A single-pole electrical switch controls a light or other load from one location, while a three-way switch setup lets users control the same load from two locations. The function is similar in residential and commercial installations, with the choice based mainly on the room layout and whether control is needed at one or two points.

Compare the switch’s voltage rating with the circuit voltage, such as 120 volts or a 120-to-277-volt range, and choose a rating that matches the intended application. Compare the amperage rating with the connected load, noting that the assortment includes 15-amp mechanical switches and an essential switch rated at 11.5 amps at 120 volts for listed lighting and motor loads.

The wireless essential switch supports automated lighting systems and provides on/off control for various lighting loads and some small motors. The mechanical electrical switches are intended for standard on-off control of lighting loads that do not use automation, with single-pole or three-way wiring options.

Before specifying electrical switches, confirm the circuit voltage and load rating, whether the application needs single-pole or three-way control, and whether the switch supports the connected load type. For wireless essential switches, check for a neutral wire, line and load connections, suitable screw terminals, and any required system or faceplate compatibility before installation.
