SPX Johnson Automatic Float Switch - AS888

SPX Johnson AS888 Automatic Float Switch converts your electric >Bilge Pump to automatic operation - simply connect the automatic switch to your >Bilge Pump.

The AS888 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.

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.
