Excavator Pressure Switch J221-82B-020000

An excavator pressure switch is a key component used to monitor and control hydraulic or lubrication system pressure in construction machinery. Its primary function is to ensure equipment operates within a safe pressure range and prevent damage caused by abnormal pressure. A pressure switch is a device that mechanically or electronically detects system pressure and controls circuit closure. It provides safety protection by monitoring key parameters such as oil pressure and hydraulic system pressure to prevent damage caused by abnormal pressure. System control automatically starts and stops related equipment or issues alarms based on pressure fluctuations. Status indication provides the operator with electrical feedback on system pressure status. Energy-saving optimization: Select models can adjust the engine operating mode based on pressure fluctuations to achieve energy-saving operation.
