1 socket switch wiring diagram

Want to know how to wire one switch to control both a light and a socket? This is a practical circuit diagram with a step-by-step explanation. The combined wiring arrangement will guarantee that there is only one point of control available, such that both the light and socket can be controlled using the same control point. It becomes useful in small rooms or workshops since it is easier to wire, and also its usage is efficient.

Formula & Table Summary:

Basic Connection Formula:

Live → Switch → Light + Socket | Neutral → Light & Socket

Component Description
Switch Single-pole one-way switch
Light 1 Ceiling or Wall-mounted Lamp
Socket 3-pin power socket
Power Supply 230V AC
Wiring Color Phase (Red), Neutral (Black), Earth (Green)

single switch socket wiring

Here is the wiring diagram on how the circuit should be installed, where there is one switch by which the lights and the sockets are controlled. It can also be applicable in cases where small spaces are available, such as rooms, corridors, or utility rooms. The switch will be attached in a manner that, when switched on, it supplies the socket and the light. A wiring in this setup eliminates the supply of power to the socket when the switch is switched off, providing an added safety measure to a temporary or controlled emplacement. This wiring diagram is easy to understand by anyone who needs to study any electrical task, as well as those who are doing their own practical electrical work.
