VDO Oil Pressure Switch Light Duty 1/8"x 27NPTF 21kPa 12/24V

This is a compact and reliable pressure switch engineered for oil and air pressure monitoring in light-duty automotive and industrial applications. This switch is normally closed (NC), meaning it maintains a closed circuit until the pressure rises to approximately 21 kPa (3 psi), at which point the contacts open to deactivate warning indicators or control systems.
