    1 way light switch wiring

    A 1-way light switch wiring is the most common and basic circuit used to control a single light from one switch. It’s commonly installed in small rooms, bathrooms, porches, or any area where only one entry point and one light fixture are present. The circuit is simple: the live (phase) wire passes through the switch to the light, and the neutral wire connects directly to the other terminal of the light bulb. When the switch is turned on, it completes the circuit and powers the light. This wiring method is suitable for both LED and incandescent bulbs and is beginner-friendly. Using proper safety measures and tools, such as a tester and wire stripper, you can install this circuit easily. It’s an essential concept in residential electrical wiring and forms the base for more advanced circuits like two-way or intermediate switching systems.
