Easily control your ceiling fan from two different switches using a two-way wiring system. Learn the wiring diagram and connection steps in this guide.
3 point lighting switch
To control 1 light with 3 switches, you will require two 2-way switches and an intermediate switch. This connection will allow you to use one light and make it work in three locations. It is ideal in an extended hallway or a staircase. The trick is to control the traveler wires at the intermediate switch and use the 2-way switches. After the connection is made in the right way, any of the switches will make the light ON or OFF.
fan control from two switches
Two-way switch wiring for a fan enables you to switch a ceiling fan by using two switches found in areas of a room apart, as at the ends of a passageway or by two doors in a bedroom. This system of wiring makes it convenient and safer, as there are several points through which the fan can be switched on or off. One has two SPDT (single pole double throw) switches separately interconnected using traveler wires and one live wire through one switch going to the fan. It is usually in staircases or bedrooms or long rooms. This wiring technique has nothing to control a fan speed; this is only an on-off switch.
how to wire fan with 2 switches
| Component | Connection |
|---|
| Switch 1 (SPDT) | Live to Common Terminal |
| Traveler Wires | Two wires between both switches |
| Switch 2 (SPDT) | Common to Fan |
| Fan | Output from switch → Neutral |

Yes, using two-way switch wiring.
What type of switches are used?
SPDT (Single Pole Double Throw) switches.
Does two-way wiring control speed?
No, it only controls ON/OFF.
Where is the regulator in this setup?
It must be connected before or after the switch system.
Can this wiring be used for lights?
Yes, it's commonly used for lights too.
Is neutral wire required at both switches?
No, only at the fan terminal.
Is it safe to install this at home?
Yes, with proper insulation and safety precautions.
Can I use this for exhaust fans?
Yes, for ON/OFF control only.
Can this be done without an electrician?
Yes, if you understand the wiring diagram properly.
What wire size is recommended?
