LeGrand (Pass & Seymour) make a multi-control single pole switch with a split tab TM8113WCC, which allows for the control of two independent circuits on a single yoke (one box). Code question: is it permissible to run a mains voltage (120V) circuit on one side of this device and a low-voltage circuit on the other?
Electrical – use a split tab switch for mains voltage and low voltage

Best Answer
This is OK provided that the wires to the fan control switch are treated as 120VAC wires as per 725.46:
(i.e. run using NM and not communications-type cable/wire) and as per 725.48(B)(1):
since the control wires are with the fan's power wires, and we can safely treat them as a Class 1 control circuit using the provisions of 725.130, Exception 2:
