I bought the Intermatic T104 208-277 Volt Mechanical Switch from Amazon. It should arrive in two days. I also ordered 2 sets of on and off tripper pins. I forgot to mention that I can manually turn on and turn off the pump and the switch isn't loose, too easy or hard to push. I can hear the timer switch on and switch off by it self. I have to unplug it to stop the timer from turning on and off by itself at random. I have been keeping the pool clean from debris, vacuumed, and brush all sides of the pool. In the meantime, I will be working on getting the proper levels of chlorine and PH and whatever else I need to do to prevent problems. I will update this thread after I get the timer installed this Saturday.
