Can I replace 12v light switches with 110v house switches?

I just remembered that I installed several 110V switches in my RV for 12V lights, it was many years ago. The RV came without any wall switches for the lights, some of the lights were difficult to reach so I installed ordinary light switches for those lights and for the bathroom exhaust fan. I have not had any problems with the switches. All of my lights are now LED but the exhaust fan is the original.
