KEY EPA - 3 WAY SWITCH (Komatsu KO3EA-55-38790)

A worn 3-way switch can cause intermittent or lost electrical connections in the circuit it controls. This aftermarket replacement part references the Komatsu catalog number KO3EA-55-38790. The switch type provides three distinct electrical positions for operator selection. A common failure consequence is that a faulty switch may fail to maintain contact, leading to erratic equipment response. During operation, the switch’s internal contacts must reliably open and close each circuit path. Verify the serial number or application, then call (562) 693-7748. The switch is a key component for controlling electrical flow in a three-position setup.
