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\n[table id=528 /]\n\nN.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.
