Abstract
The invention contemplates a float-operated electrical switching system with two fluid-level indications and with provision for mechanical adjustment of the difference in elevation between the two indicating points. The switches are magnetically actuated in accordance with proximity of a permanent magnet carried by the float. The float is guided on an upright magnetically transparent tube which houses the switches, and for at least one of the switches mechanical adjustment of elevation within the tube is available via external access at the upper end of the tube.
