This simple waft switch monitors the water level for your sump pump and allows you to know if the water level rises or falls. Connect it to a warning device or alarm system for an extremely low cost sump pump alarm. The switch may also be connected to relays and other devices to drive high current quite a bit. Offering high reliability, the bobber’s sealed reed switch provides high isolation when pump wiring breaks down. The switch operates even if totally submerged and its stainless steel hose clamp allows easy level adjustment. Its unique reversible waft allows for an N.O. or N.C. switch circuit. It fits virtually all sizes and sorts of return pipes, and comes complete with a stainless-steel hose clamp and 20 lead wire.
