Good To Know
Q: How do I know if my oil pressure switch is faulty? A: A faulty switch often causes the oil pressure light to stay on constantly or never come on, even when the ignition is on. Testing the switch with a multimeter can confirm if it is opening or closing correctly.
Q: Can this oil pressure switch be used on other engines? A: It is specifically designed for Yanmar engines, but it may fit other engines with the same thread and electrical specifications. Always verify your thread size and switch behavior before installing.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
