SPX Automatic Switch – AS888

For full automatic bilge pumping operation, connect the automatic switch to your bilge pump. The AS888 automatic switch has a time-proven micro switch without mercury. When water exceeds the acceptable level, the pump is turned on by a rolling steel ball, which changes the pressure on the micro switch. The AS888 attaches to any of SPX’s Johnson Pump marine brand bilge pumps through the clip on “T-slot” and can be used with 12V and 24V systems.

N.B. As with all submersible electrics, attention is needed during installation to ensure that wiring connections remain above water level. Specified output is US gph open flow.
