Reply to comment by boxsterguy in Can I install this single pole switch in place of the dimmer switch that was here? by Affectionate_Cronut

Yerp. Sometimes still done today. It's not up to code as we need a neutral in the switch box.(Now) Black feed white switch loop. Neutral already existing at the light connected to another point in the same circuit (hopefully).

Edit: You can't always go off color of wires. I wire 3 and 4 way switches using white wire.(14-3 with ground) I identify with tape. Some electricians don't.

Worst case scenario, voltage detectors (or your fingers) don't lie. Turn on the power, check the wires, see what's energized when the switch is off.

Meter, fingers, apprentice, metal grounded box whatever is closest. If it's early AM fingers is the best for a wakeup.
