What is the loop for on a light switch?
The main method of wiring lights is to use the ‘loop at the light’ method. Batten and rose light mountings provide additional blank terminals used to join (loop) wires. In most lighting installations 3 core thermoplastic sheath (TPS) cable is used to supply power directly to the light mounting.
Can one switch control 2 lights?
You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a “home run” configuration.
What are two switches that control one light called?
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location. A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
