The LV41 Series Sump Float is a mercury‐free mechanically actuated floating switch intended to activate
electrical components, usually pumps, to start and stop automatically. The LV41 series is perfect for simple
level control of liquids for filling or draining reservoirs and tanks. Float switches such as the LV41 series are
the most universally used for pump automation, due to their high reliability, economical pricing, and easy
installation.
The LV42 Series Waste Water Sump Level Switch is a mercury‐free self counter‐weighted floating switch
designed for the automation of pumps, specifically filling and draining of tanks, wells, and reservoirs. The LV42
series body is free of any irregularities making it ideal for use in sewage water applications. The polypropylene
body consists of a double airtight chamber with high‐pressure melted polypropylene re‐injection sealing to
ensure a perfect seal against infiltration.
Counterweights and cable hangers are available to suit a variety of mounting applications.
