DUNGS GW 500 A6 | Gas Pressure Switch

The pressure switch GW…A6 is an adjustable compact pressure switch according to EN 1854 for combustion plants.
The pressure switches are suitable for switch-on, switch-off and switch-over of an electric circuit at a variable pressure actual value, relative to the set desired value.The setpoint (switching point) is set on an adjusting wheel with scale. A test nipple is integrated in the metal housing as standard.
