For full automatic bilge pumping operation connect the automatic switch to your bilge pump. 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. May be attached to any Johnson bilge pump through the slide on “T” – slot for 12 or 24V systems.
