The Landon Kingsway mercury switches are designed to be used in conjunction with our Free-Fall Fire Valves to provide position sensing or to cut power to oil burner pump motors in the event of a fire. The unit is available in both a single and three-phase style although the three connections on the three-phase version could be used to control three single-phase devices. Both versions contain contacts that remain closed while the valve is in its’ normal state (one contact on the single-phase, 3 on the 3-phase) and a separate normally open contact that is suitable for sounding an alarm as it closes if the valve lever drops.
