Single-Gang One-Way Switch
A single-gang one-way switch controls a light or electrical appliance from one location. It is commonly used in standard residential installations.
Single-Gang Two-Way Switch
A pair of single-gang two-way switches allows the same light or electrical appliance to be controlled from two locations. For example, one switch can be installed near the living room or hallway entrance and the other near a seating area, allowing the light to be turned on or off from either location.
In a bedroom, switches can be installed at the entrance and beside the bed to control the main light conveniently.
Remote-control switching is another option. When choosing a system, confirm its compatibility with the connected load, installation requirements, and warranty coverage.
