SMF19 pressure switches provide time tested, reliable control for
automatic water systems. The switch is universally acceptable for
use as original equipment on water well pumps or pumping systems.
It is available with an On-Off knob for manual cut off the pump.
SMF19 pressure switches can also be used to regulate the tank

prevents compressors from starting under load, and it is available
with an On-Off knob for manual cut off the compressor.
