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

FAQ

Questions

Question

How are the F6 & F7 vertical level switches converted from N.O. to N.C. or vice versa?

Answer

The float is removed and replaced upside down.

Question

Why is the minimum specific gravity important on the float level switches?

Answer

If a medium has a lower s.g. than the rated minimum for a float, the float will sink through the media and the switch will not operate.
