SPX Johnson Pump 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 pump through the clip on "T-slot" and can be used with 12V and 24V systems.
