This compact, rugged switch utilizes a snap–acting stainless steel diaphragm that
reverses its curvature when pressurized to a customer specified actuation pressure. When
the disc snaps it opens or closes a set of electrical contacts by means of a transfer pin.
Resetting the switch occurs automatically when pressure drops below the release value.
The unique latching mechanism in the 29PS design assures safe electrical cutout even if the
reset button is held fully depressed. This trip–free design prevents the consumer from restarting
the equipment until the line pressure has dropped below the release setpoint.
