W.E. Anderson® Vertical Level Switch, F7-K, PFDF Float and Stem

Series F7 & F7 Compact Level Switches combine low cost and reliability with fast, simple installation. Hermetically sealed reed switches are actuated by magnets permanently bonded inside the float and can be easily adapted to open or close a circuit on rising or falling levels. Vertical mount models are shipped with normally open switch contacts, which close as the float rises toward the mounting threads. Reverse switch action by removing the float, rotating it end-for-end, and replacing it on the stem. Vertical models mount internally, oriented within 30° of vertical, or select optional fittings for external mounting. Switch ratings are suitable for many solid state control systems and monitors or alarms. Simple relay interfaces can be used for higher current applications.
