double piggyback variable level float switch (VLFS) can convert a 115 V nonautomatic pump into an automatic pump. The pump must not draw over 13 Amps of current. The advantage to the double piggyback float is the on/off points are adjustable maximizing the run time in the tank. With this float switch, you can locate it wherever needed to get the job done. The double piggyback switch is normally open when hanging vertically above the liquid level. As the water level rises it'll call the pump to run. The float that encases the mechanical switch is constructed of durable PVC/polypropylene. The standard cord length is 15' which is more than enough for most basin or tank pumping applications.
