OMEGA’s PSW601 Series switches
are designed to provide long, stable
life. They use a thin-film sensor with
a minimum life of 1 million cycles.
Solid state circuitry analyzes the
signal from the sensor to activate
the switch at the setpoint.
Deadbands are adjustable from

0.1 to 95% of range, and status
lights give a visual indication of
switch status.
