Pressure switch for Demag AC 615

This pressure switch, part number 32390040, functions as an electromechanical sensor within the control systems of the Demag AC 615 all-terrain crane. It is integrated into the gear shift lever assembly to detect specific fluid pressure levels. When the system reaches or exceeds the calibrated pressure threshold, the switch activates or deactivates an electrical circuit, facilitating the automated gear shifting process required for the transmission to operate correctly.

This component is compatible with the Demag AC 615 crane model. It is designed to meet the specific pressure requirements of the transmission control system, ensuring that gear changes occur only under the appropriate operating conditions. Proper function of this sensor is necessary to maintain transmission performance and prevent erratic gear selection or operational failures that could impact the movement of the crane.

In heavy machinery, pressure switches typically utilize an internal diaphragm or piston mechanism that reacts to fluid pressure to trigger an electrical contact. By monitoring these levels, the switch provides feedback to the machine's control system, allowing for precise management of hydraulic or pneumatic functions. Maintaining the integrity of these sensors is a standard part of transmission system upkeep to ensure consistent machine operation.
