switch

I just set up my vacuum chamber (pressure cooker pot with a diaphragm pump.) It holds vacuum well, so well, in fact, that I'd like to not have to run the pump continuously. Anyone know of a reasonably priced programmable vacuum switch so I can turn the pump on and off as needed? Thanks, Gary

I have an older Turncrafter lathe and yesterday when I was moving it I bumped it against my jointer. Now today when I went to use it, it didn't turn on right away when I flipped the switch. Then I clicked it on and off a few times and it worked. After about a dozen more on and offs it stopped...
