Jon,
If you have the chance, please give me some pointers in wiring up two float switches...
I have two of the Grainger switches you had listed in your article. I'm using one right now (for about 1 year now) in the sump to turn a small topoff pump on/off. The wires from the switch are basically connected to a plug (to wall for 120v) and outlet. A pump in turn connects to the outlet. When the switch is in its lower position, it completes the circuit and the pump turns on.
To be double as safe, I want to use the second switch, wire the switches together (somehow). If the first switch fails and fills too much water into the sump, the second switch will cut the connection and thus turning off the topoff pump. Is this type of wiring possible?
Thanks in advance.
