I have a drinking fountain which I have wired up to turn on and off with a foot pedal. The pedal is a simple mono plug piano pedal that is wired up to the switches behind the paddle buttons of the drinking fountain. However, there's one thing I didn't exactly think about - the paddle button switches are 110V AC. So, I now have a pedal switch with 110V running through it sitting on the floor. That's . . . a little unsafe, I'd think.
I know I could easily get a relay, a AC/DC wall wart, and create a little low-voltage switch to make this safe and functional. However, I wondered if there's a ~$10 single board turnkey solution out there which would do what I need - pinouts for mains, a transformer/AC/DC converter to step the voltage down to something safe, and a relay which switches on the low-voltage to control the 110V. Is there something out there like that? Probably a better question: is there a better way to solve my problem which I haven't considered?
Thanks!
