Oil pressure switch for Mitsubishi FD25

The oil pressure switch, part number MC840219, serves as an electromechanical component within the engine lubrication system. Its primary function involves monitoring the oil pressure inside the engine and transmitting an electrical signal to the control system or instrument panel if the pressure drops below a specified safety threshold. This mechanism acts as a monitoring device, alerting the operator to potential lubrication system issues to prevent engine damage.

This component is designed for Mitsubishi equipment, specifically fitting the FD25 and FD80 forklift models. Compatibility with these units ensures proper integration into the electrical and lubrication circuits of the machine, facilitating accurate pressure readings and timely alerts during operation.

An oil pressure switch typically utilizes an internal diaphragm or piston that reacts to oil pressure changes. This movement engages or disengages an electrical contact to open or close a circuit. The device is engineered to withstand the operational temperatures and oil exposure found within the engine environment. Maintaining the correct switching threshold is necessary to ensure that alerts trigger only when the oil pressure falls outside of normal operating parameters.
