HORN BUTTON (Komatsu KO304-40-31420)

A worn horn button can prevent the operator from sounding the horn, creating a safety hazard in busy environments. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO304-40-31420. The horn button is a switch that completes an electrical circuit when pressed, activating the horn. A failed button may leave the horn silent, reducing the operator's ability to alert nearby personnel. During a pre-shift check, a horn button that feels loose or unresponsive should be replaced promptly. The item ships at approximately 0.1 pounds. Verify the serial number or application, then call (562) 693-7748.
