    Bedroom electrical switch

    The bed switch wiring is a typical installation in most modern households that will enable the lights or fans to be controlled at the bedside. Using two-way switches and adequate wiring of the same, users are able to switch bedroom lights on/off at the door and off the bed with only two switches. This guide will show how the connection is supposed to work, give diagrams, and emphasize some safety tips. It suits electricians, weekend warriors, or any other person wishing to make life in the bedroom more convenient and comfortable.

    3 pin socket wiring diagram

    A 3-pin socket is commonly used to power electrical appliances that require grounding for safety. It has three terminals: Live (L), Neutral (N), and Earth (E). The live wire carries current to the appliance, the neutral wire completes the circuit, and the earth wire provides a path to ground in case of leakage. The earth pin is slightly longer and thicker, ensuring it's the first to connect for safety. This socket is standard in most household and office outlets for devices like refrigerators, computers, and ovens.
