SWITCH - IGNITION (Komatsu KO3EB-55-16190)

KO3EB-55-16190: A failing ignition switch can prevent the starting circuit from engaging, leaving the equipment inoperable. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3EB-55-16190. The switch controls the flow of electrical power to the starter solenoid when the key is turned. Over time, internal contacts may wear, causing intermittent or no electrical connection. A worn switch may also fail to hold the start position, requiring repeated attempts to crank. Verify the serial number or application, then call (562) 693-7748.
