Over time, I have become so used to using either 230vac, or 12vdc / 24vdc energized coils, depending on the project I am working on. Recently, I wanted to build an automatic switch that would turn off both water pumps, in the event of a low sump water level. I found some relays and sockets, and quickly ordered them - without putting much thought into them. Fast forward three weeks. Received relays and s
