Jabsco 59400-0012 Hydro Air Bilge Switch, 12V
The Jabsco 59400-0012 Hydro Air Bilge Switch, 12V combines the flow, pressure and electrical characteristics of its spec sheet with the corrosion resistance a marine installation demands. Its full specification is 12V DC, 20A max switched current, air-pressure activated diaphragm switch with no submerged electrical components, mercury-free, ISO 8846 marine ignition protected, activates at 2-1/4 in bilge water rise, diaphragm switch mounts up to 10 ft above the plastic air bell.
Installation and long-term reliability both come down to matching this unit to the plumbing or ducting it is replacing, and to protecting the electrical side with a correctly sized fuse or breaker rather than relying on the unit alone. Like any Jabsco product, it draws on decades of marine-specific engineering, so a factory replacement performs to the same standard as the original equipment it replaces, without the compromises of a generic substitute.

Frequently Asked Questions
Q: Can this run dry without damage?
Check the run-dry note in the specifications above. Where it is listed as run-dry capable, brief dry running will not damage it, but running dry for extended periods is never good practice.
Q: Will this replace my existing unit without changing the plumbing or ducting?
In most cases yes, provided the port size matches. Compare the port dimensions in the specifications above against what you are removing before ordering.
Q: Is this suitable for continuous duty?
Check the duty cycle in the specifications above. Some models in this family are intermittent-duty only and will trip their thermal protection if run continuously.
Q: Do you carry service parts for this unit?
Yes, service parts for this product are stocked separately. Send us your unit model number and we can point you to what you need.
