I'm looking for some sort of accumulating timer I can wire up to each vac motor in my SS vacs to keep track of minutes/hours used. So it would have a display that displays the amount of minutes/hours. Probably similar to maybe what diskin uses when they offer to put a timer on one of your air shammee units to measure usage. I'd like it to be resettable. The idea is to periodically check each vac motor usage, and change the brushes on the vac motor at x amounts of minutes/hours. Then reset the timer, and do it all over again.
Any thoughts on a timer that would work for this?
