echnical Specification
The SH-3 series are NPT mount horizontal
float operated level switches.
This design uses a pivoted float arm with a
magnet on the inboard end. This magnet
when moved by the rising float arm
interacts with another magnet in the
switch enclosure to give a snap action
operation.
Two switching options are available using
either microswitches or reed switches, for
different switching power and operating
temperature ranges.
Available with either 1 1/2”NPT or 2” NPT
thread mounting.
