How To Have Two Switches With One Exhaust Fan (Explained)

It is important to maximize how the exhaust fan works when it is set up.

A lot of people don’t take the time to analyze what their options are and that is what holds them back from getting a good exhaust fan setup.

The goal is to ensure you are taking the right steps to do things the right way. This means analyzing what works and what does not.

The main requirement people have is needing two switches with one exhaust fan.

To set up two switches with one exhaust fan, you will require two double-pole switches. Connect one pole from each to the damper and one pole to the fan. This will help provide control across two switches.

When you are doing this, you will want to make sure the connection is running parallel to each other.

This is how you are going to get the switches to work as you want them to.

This guide is going to show you more about what to do when setting up two switches with one exhaust fan.

Steps To Have Two Switches With One Exhaust Fan

1. Set Up Two Double-Pole Switches

To make this a possibility, you will need to set up two double-pole switches.

Make sure you are getting the right double-pole switches, which are going to work well in the setup.

You are also going to want to ensure they are installed in the right spot. Otherwise, they are not going to function as you want them to.

Look at keeping them within a reasonable distance as that is going to make it a lot easier to connect the switches to the exhaust fan.

The right double-pole switches are a must for this to work.

2. Run One Pole On Each Switch To The Damper

When you have the double-pole switches in place, you are now going to start thinking about completing the connection.

The connection has to be done in a specific way or one of them won’t work.

This is going to start by looking at how the switch is set up.

The switch is going to have two poles. Each pole is going to have to connect to something within the circuit.

The first pole on both switches will need to go to the damper. You will want to make sure both are running parallel while doing this.

This connection is going to have to go to the damper as the first point of control for how the switch is going to work.

This goes for both switches.

3. Run Second Pole On Each Switch To The Fan

Now, you are going to take a look at the second pole on each switch.

The second pole has to go to the exhaust fan.

You are going to want to make sure this is set up in a way where they are connecting at the right point and will work when the switch is used to activate the fan.

This includes ensuring the connection is secure.

You can also do this when you are testing the switches later to ensure things are in the right shape moving forward.

4. Switches Should Run Parallel To Each Other

The last step to think about will be how the double-pole switches are set up.

This includes how the poles are interlinked.

The purpose of going down this path has to do with making sure the connection is well-synced. You can’t have a situation where it is not in line with what you need as that is going to take away from what you are hoping for.

You will want to make sure the switch is done the right way.

This includes keeping both switches running parallel to each other. This is a must.

If you don’t take the time to do this, the switches will not work out as planned.

Final Thoughts

These are the details you need to look at when setting up two switches for one exhaust fan.

If you are looking to set up two switches for one exhaust fan, you will need to invest in two double-pole switches. One pole from each switch will go the damper, while the second pole will go to the fan. These will need to be parallel to each other to work.

You will need to take your time laying out the plan for how the two double-pole switches are going to be installed.

It is best to have a map for how you are going to run the connections based on the layout of the room and where the exhaust fan is.
