Conmutable wiring allows controlling a single light from two switches, ideal for staircases or hallways, using two-way (SPDT) switches for convenience and safety.
electrical wiring 3 lights diagram
The process of connecting 3 lights to 3 individual switches is very basic in residential and business electrical setup. The lights have individually dedicated switches so that one can have full control and energy savings. The wiring part is clearly explained by diagrams, simplified formula and illustration of sample input-output table all of which are easy to comprehend, follow and implement by a beginner.
Conmutable circuit explanation
Commutable wiring is where all wiring can be switched by two or more switches to operate one point of light. This is mostly applied in staircases and in corridors or in big rooms where there are more than one entrance points. It also enables users to switch on or switch off lights at different places conveniently. The simple one would be employing SPDT (two-way) switches and proper wiring in between the switches. The wiring diagram will vary depending on the installation (2-way or 3-way), and the aim will be the same: to provide the user convenience and to save energy.

What is conmutable wiring?
It allows a light to be controlled from two or more switches using two-way or intermediate switches.
Where is conmutable wiring used?
Commonly used in stairways, corridors, or large rooms with multiple entrances.
Which switch is used in conmutable wiring?
Two-way (SPDT) switches are used, and sometimes intermediate switches for 3-point control.
How does a two-way switch work?
It redirects the circuit between two traveler wires, enabling ON/OFF from different locations.
Is conmutable wiring safe?
Yes, when done correctly with proper insulation and earthing.
Can I control a fan with conmutable wiring?
Technically yes, but usually it is used for lighting control.
How many switches can I use in conmutable wiring?
Up to 3 or more using intermediate switches between two-way switches.
What wire is needed for conmutable wiring?
Typically 1.5mm² copper wire for lighting circuits.
What are traveler wires?
Wires connecting terminals between the two switches in the setup.
Do I need an electrician for this setup?
It's recommended unless you're confident with safe electrical practices.
