Remove the wall plate of the existing switch by either snapping it off or unscrewing it. Unscrew the existing switch from the electrical box and slowly pull it out just enough to reveal the wires connected to it. If you see a white wire, or a group of them, then you have neutral wiring.
Do all light switches have a neutral wire?
Standard rocker and toggle switches will not have a neutral wire connected. If you do find a white wire connected to a rocker or toggle switch, it is likely not a neutral wire. You can check out our support article on common switches to help identify which wire this will be.

What is neutral wire on light switch?
The neutral wire allows the completion of the circuit and the switch to have power even when it’s turned to the off position when you want the lights off.

Will an outlet work without a neutral?
If there’s an open neutral, the outlets won’t work, but they will still be energized. Use a plug-in circuit tester to check for an open hot or open neutral. If a string of lights or outlets tests for open neutral, you’ll probably find the disconnection in the device closest to the panel.
How do I find an open neutral wire in my house?
If a tester reveals Hotness still present at more than one dead item of the circuit (at the shorter slot of receptacles or the tongue in the bottom of a turned-on standard light socket, for instance), the neutral is open.
