Product Description
SJE MilliAmpMaster™ WPS Control Switch | Narrow Angle, Low Current Float Switch for Potable Water SystemsPrecision Float Switch for Low Current AC/DC Control in Potable Water ApplicationsUpgrade your potable water control systems with the SJE Rhombus MilliAmpMaster™ WPS, a mechanically-activated narrow-angle float switch specifically designed for low current, non-arcing applications. Ideal for PLC panels, alarm systems, and solar-powered controls, this float switch delivers dependable performance in drinking water systems, tanks, and reservoirs.Its sealed gold cross-point contacts ensure consistent, accurate switching at extremely low amperage—down to just 0.160 mA at 125 VAC—making it an essential tool for environments where standard switches are not suitable. NSF/ANSI 61 certification and CSA approval ensure safety and compliance for potable water tanks of 250 gallons (950L) or more.Key Features: Precision for Low Current Control
Low Current Compatibility: Engineered for control applications as low as 0.160 mA, ideal for sensitive circuits and non-arcing devices.
SPDT Wiring Flexibility: 3-wire design allows use as either normally open (N.O.) or normally closed (N.C.), adaptable to a variety of system configurations.
Gold Cross-Point Contacts: Provide precise, long-lasting switching in low current environments.
Narrow Angle Activation: Activates/deactivates approx. 1.5" (3.8 cm) above/below horizontal with a short 3.5" (9 cm) tether, offering stable control even in confined tanks.
NSF/ANSI 61 Certified: Approved for use in drinking water applications—safe and compliant.
CSA & UL Listed: Third-party tested to meet North American performance and safety standards.
Bright Orange Cap: For easy visual identification in crowded control panel setups.
5-Year Limited Warranty: Long-term reliability you can trust.
