The PSW-850 is a simple,
economical control for processes
that require multiple switching
capabilities. Dual or triple switch
controls provide multi-outputs in
applications such as alarm and
shutdown, pre-alarm and alarm,
high/low limit, and level staging
functions.
Triple-switch models have been
used for liquid level control. In this
application, 3 pressure settings
correspond to “pumping out”
elevations in a sump pump.
