all switches do NOT require a neutral, not in any code I'm familiar with. your definition of properly is half baked and people reading should factor this when considering your comments.

while smart switches/ thermostats will require what acts as a neutral, switches in general do not. and depending on wiring, is completely unnecessary as to use the neutral you'd be doing major rewiring anyways. next you'll say we have to run a traveler or 2 to every box requiring 3 or 4 conductors when 2 suffice just in case, ignoring the need for breakers. some things do NOT need the ability for a smart switch due to safety, and thus neutral.

Switches do not require a neutral. Only light switch boxes require one to be available.

Keyword light. Not switch.

Edit: NEC 404.2C is what you're trying to quote... Other people alsoprovided the exact code in the comments here.

you missed the point and you're wrong. light switches complete a circuit when on, they find a neutral [or return] when on, when off they interupt that return, whether that's a correct or incorrect wiring method can vary.

an always on device requires a neutral OR alternative power. this means smart switches, smart thermostats, automated function devices.

if this were a multi phase wiring install that COULD differ.

please don't input incorrect or half right information. yes lights get the neutral passed to them, but convention has changed if you intend to automate. you're fully right if this were 1990 again.
