I have a whole home attic fan. It’s old I’m guessing it’s original with the house from 1962. My wife wants to switch out the switch for something more modern. Currently it’s just an on off timer dial. I put some picks below of the switch and fan. Can buy any modern on off timer switch like something with a digital display to switch it out with? Please feel free to send links and suggestions to switches that will work! Thanks for your help!
