The SJE Double Float Master Piggyback Float Switch Assembly consists of a connected pair of non-mercury mechanical float switches designed for direct control of 120 volt pumps up to 3/4 HP. This float switch assembly is designed for applications requiring an accurate pumping range in small diameter pits and vessels. It can be used in both calm and turbulent applications, and has an adjustable pump down range of 3" to 48". Mounting clamps are included.
The Double Float Master Float Switch Assembly consists of two mechanical float switches and a waterproof splice tube. The splice tube contains a holding relay which enables the floats to function in series and eliminates pump chatter.
The piggyback switch feature allows any 120 Volt pump to be connected directly to the double float switch assembly, eliminating the requirement for a control panel and relays to control the pump on and off functions. The pump can also be unplugged from the double float switch assembly when automatic control is not required, and can be plugged into the 120 Volt receptacle for manual pump operation. Available cable lengths are 15', 20' and 30'.
SJE Double Float Master Piggyback Float Switch Assembly is UL and CSA listed and NSF-61 rated. It carries a 5-year manufacturer's warranty.
