SPX Johnson pump - Automatic switch AS888
For fully automatic operation of the bilge pumps, connect the automatic switch to your bilge pump.
The Johnson AS888 automatic switch has a proven mercury-free microswitch.
When water rises above an acceptable level, the pump is switched on via a rolling metal ball that changes the pressure on the microswitch.
The Johnson AS888 can be attached to the "T-gap" of any bilge pump with the clip and can be operated with 6, 12, 24 or 32 V systems.
Use Johnson AS888 for a better and safer life at sea!
