I'm planning on setting up a well storage tank for my well. I have learned a lot on this forum. More than on any other website. But I just want to clarify something. The well pump is currently controlled by a pressure switch. The pressure switch opens and closes both the L1 and L2 circuits. I have always assumed that was necessary. But it seems that a float switch opens only one circuit. Am I understanding that correctly? That only one circuit needs to open and close to start and stop the pump.
