Learn how to wire a corridor lighting system using switches at both ends. Ideal for homes, offices, and hotels to control lights from multiple points.

A 1-light, 4-switch circuit connection can enable you to switch a light on or off at any of four switches. This is done by use of two (2) 2-way (SPDT) switches and two intermediate switches (DPDT or 4-way). This installation is often in a large hall or staircase when there are several access points to the light in question. The wiring layout and the way the switches link are imperative to shun confusion or short circuits. The simplified explanation and diagram are given below, which can be followed easily.
corridor switch wiring
A corridor wiring system is a very effective way of mastering a single light at two or more access points or stations, and it is generally applied in long corridors, stairs, and large rooms. Such a system meets the requirements of convenience and energy saving because the users are able to switch off or switch on lights at one end of the corridor or the other. The regular setup is 2-way or intermediate switches, depending on the control points. It is an absolute layout in a residential and commercial place, such as a hotel and an office, where it is required to control lighting in various access points. Being familiar with this wiring can aid anytime anyone would like to do some DIY electrical skills or troubleshooting/implementation of corridor lighting.
