This 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. Attaches to any Johnson Pump bilge pump through the clip on "T-slot" and can be used with any 6, 12, 24 or 32 V systems.
