Question about Smith A. O. Single Speed J-Frame Threaded Shaft Full-Rated Motors for Hayward Northstar Pumps - 1 HP
My idea is to design circuit to automatic shut down pump when pump loses vacuum.. So far I have contactor either with 24 coil or 110v coil in series with vacuum switch.My problem is circuit will not close upon time clock starting pump because vacuum switch has no vacuum.If I could temporary short vacuum switch with time delay it would than be able to shut pump down if it lost vacuum for some reason. Any ideas
A momentary contact switch can be used to bypass the vacuum switch until operating pressures and vacuums are reached. It is called a start switch.

You need to install a time delay relay.
