Barb, 21A, 24/240v, 1-5 PSI

The Len Gordon 800125-3 is a universal barbed pressure switch rated at 21 amps, compatible with 24V and 240V spa systems. Pressure switches are safety devices that measure water pressure inside the spa heater as an approximation of water flow, and shut the heater down when low or no flow is detected — protecting against heater meltdown and unsafe water temperatures. This SPDT switch features a 3/16" hose barb water connection and is factory set with a 2.5 lb differential to eliminate relay chatter. Adjustable from 1-5 PSI. Compatible with Balboa, Gecko, and most standard spa control systems.
