Madison Company's single-point liquid level float switches feature visual NO normally open) / NC (normally closed) operation indication. The proven reliability of the magnetic float switch technology assures repeatability (up to 5 million cycles) at an economical price. Among typical applications are alarm circuits that control motor starters, contactors, solenoids and relays.

Madison manufactures vertical, horizontal and side-mounted versions. Full-size switches feature larger floats (typically 1-1/2" to 2" diameter) that provide greater buoyancy for use in liquids that have lower specific gravities. The smaller size of the miniature switches (1" diameter) and subminiature switches make them ideal for limited-space applications.

The choice of float materials for single-point switches ranges from stainless steel and Buna-N to polypropylene, PBT and Teflon. Stem materials include:

Stainless steel – perfect for such industrial and OEM applications as food, appliance, medical, petrochemical and water/wastewater
Brass – designed for use with hydrocarbons
Polypropylene – ideal for many general-purpose applications or those involving highly acidic liquids.
Teflon – to meet requirements for high-purity or resistance to aggressive solvents, oils or steam.
