FN20 – “E” Series Mechanical Sump Switch
A durable sump pump float switches commonly found in most sump pumps, septic tanks, and basement pumps.
Product Description
The FN20 “E” Series Sump Float Switch is a foam-filled, polypropylene covered sump fluid sensor that is commonly used in domestic applications like sump or basement pumps. This sump float switch may also be used for septic tanks and ejector pumps. The new foam-filled sump switch design has greatly improved the life span of these mechanical floats. The foam filling protects the mechanism which prevents it from breaking in transit or from rough handling around the tank.
These float switches are fully customizable to meet a variety of commercial, industrial, or other uses. Sump level switches are durable, making them ideal for direct pump control up to 1/2 HP at 120 VAC or 1 HP at 240 VAC. Standard features include a 20’ foot 16/2 SJOW Cable with 120 VAC plug and a stainless steel pipe clamp mounting assembly.
These variable-level single ball float switches feature piggyback design and simple on/off functionality and are ideal for consumer or industrial use. While sump switch failure is common among many commercial brands, rest assured that SMD Fluid Controls offers superior craftsmanship alongside the kind of reasonable prices you expect from national brands.

A Pump Up Float Switch, also known as ‘Normally Closed’, opens the circuit on the rise and is typically used to turn the pump off when the float is in the up position. So, a pump could be set to turn off when the water level in the storage tank reaches a predetermined high level. Therefore, a pump-up float switch is often used to fill a water tank.
A Pump Down Float Switch, also known as ‘Normally Open’, closes the circuit on the rise and is typically used to turn the pump off when the float is in the down position. So, a pump could be set to turn off when the water level in the storage tank reaches a predetermined low level. Therefore, a pump down float switch is often used to empty a water tank.
• Normally Open = Pump Down
• Normally Closed = Pump Up
