Pressure switch for Link-Belt LS218H

The pressure switch, part number 0734, serves as an electro-mechanical component within the hydraulic systems of the Link-Belt LS218H crawler crane. Its primary function involves monitoring fluid pressure levels within a hydraulic circuit and activating or deactivating an electrical contact once a pre-set pressure threshold is reached. This action allows the machine control system to respond by triggering alarms, halting specific functions, or engaging auxiliary components to maintain safe operation.

This component is specifically engineered for the Link-Belt LS218H lattice boom crawler crane. Compatibility with this model ensures that the switch adheres to the pressure ranges and electrical specifications required for accurate system monitoring. Pressure switches generally utilize an internal diaphragm or piston mechanism that reacts to fluid pressure changes to actuate a microswitch. This design ensures that the hydraulic system remains within defined operational limits, preventing potential damage to pumps or other sensitive hydraulic hardware caused by incorrect pressure levels or operation outside of safe parameters.
