15 ft Variable Level Adjustable Weight Mechanical Float Switch, Black

SPECIAL ORDER ITEM. Review Returns Policy before purchase. Zoeller Pump's variable level control switches can be used to monitor liquid level conditions and activate control panels or alarms in pump chambers, dose tanks, sump pump basins, holding tanks, lift stations, and other non-potable water applications. The variable level control switch is normally open when hanging vertically above the liquid level. When the water level rises and the switch is raised a few degrees above the horizontal position the switch closes, completing the circuit to the control panel or alarm. The float that encases the mechanical switch is constructed of durable PVC/polypropylene.
