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,
