Level Switches Vertical (Series F6 & F7)

level switches vertical (series f6 & f7)

series f6 & f7 level switches - vertical

low cost, reliable and compact, hermetically sealed contacts

the series f6 & f7 vertical level switches are designed to be mounted at the maximum or minimum level point to provide level indication and control. Models are shipped with normally open switch contacts which close as the float rises toward the mounting threads.

features

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

easily 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
