Pressure Switch device is designed to drive lock-up devices to safety shut down position in the event of supply air pressure drop, whe it falls below the operating safety value.

The switching value is easily adjustable and the device allows maintainers to set the switching pressure required to activate the switch in the safety/shut down function.

The switching device operates immediately, even in the case of a gradual air-pressure decrease. After the air failure event, the device will automatically reset when the suplly pressure will be 1 bar greater than the set pressure, avoiding instability around the device set point.
