When water exceeds the acceptable level, the pump is turned on by a rolling steel ball, which changes the pressure on the micro switch. For fully automatic bilge pumping operation, connect the automatic switch to your bilge pump.
The AS888 attaches to any SPX FLOW Johnson Pump bilge pump through a clip on ”T-slot”.
Suitable for pumps of 12, 24 or 32V systems, up to 15A.
