Electrical wall switches are common devices used to control the flow of electrical power to lighting fixtures, ceiling fans, outlets, and other electrical appliances in buildings. They serve as a means to turn on or off the power supply to specific circuits, providing convenience and control over lighting and other devices. Here are some key points about electrical wall switches:
Types of Wall Switches:
1. Single-Pole Switches: The most common type, controlling power to a single fixture or outlet from one location.
2. Double-Pole Switches: These switches control a single fixture from two locations, commonly used in stairways or large rooms with multiple entry points.
3. Three-Way and Four-Way Switches: Three-way switches control a single fixture from two different locations, while four-way switches control the same fixture from three or more locations.
4. Dimmer Switches: These switches allow for adjusting the brightness of compatible lights, offering versatility and mood control.
