The Series CFS2 Cable Float Switch is a mechanically actuated floating switch
intended to activate electrical components, usually pumps, to start and stop automatically.
The CFS2 is perfect for simple level control of liquids for filling or draining reservoirs and
tanks. Float switches such as the CFS2 are the most universally used for pump automation,
due to their high reliability, economical pricing, and easy installation. Counterweights and
cable hangers are available to suit a variety of mounting applications. Optional cables
available include those with UL/CSA approval, higher chemical compatibility, high
temperature durability, oil resistance, and drinking water suitability. Contact factory for
piggyback plug option, gold contact switch option and cable length options ranging from
10 to 70 ft (3.04 to 21.34 m).

Level Switches,
Float
The Series FSW2 Free-Floating Level Switch is a mercury-free self counterweighted floating switch designed for the automation of pumps, specifically filling and
draining of tanks, wells, and reservoirs. The FSW2 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. Cable hangers are available to suit a variety of
mounting applications. Featuring CE approval and optional cables available that include
higher chemical compatibility, high temperature durability, oil resistance, and drinking
water suitability. Contact factory for piggyback plug option, and cable length options
