Komatsu 3FD-55-21470 SWITCH for FD50/60-7 & FD70 Forklifts

Overview

The Komatsu 3FD-55-21470 SWITCH is a replacement electrical switch for Komatsu large-capacity pneumatic tire forklifts in the FD50/60/70 series. Switches are small but mission-critical components: when one wears out, operators may face intermittent faults, warning lights or a complete loss of function in the affected circuit. Fitting the correct 3FD-55-21470 SWITCH restores reliable circuit operation and helps keep your Komatsu trucks working instead of sitting idle.

Compatibility

This switch fits a wide span of Komatsu internal combustion forklifts across the -7 and -8 generations, grouped into the following series:

• FD50/60-7 series – 7-series 5–6 ton trucks, including the FD50E/60E-7
• FD50/60-8 series – 8-series 5–6 ton trucks, including the FD50/60-8-EC
• FD70-7 series – 7-series 7-ton trucks, including the FD70-7-US
• FD70-8 series – 8-series 7-ton trucks, including the FD70-8-US

The 3FD-55-21470 for FD50/60-7 and its sister models is a common service item across this range, but switch configurations can vary within a series. No OEM cross-reference numbers were provided for this listing, so we recommend confirming your model and serial number with our team before ordering.

Quality and Reliability

Komatsu builds the FD50/60/70 series for demanding material handling, and replacement components need to keep pace. This switch is sourced to match the original Komatsu part in fit, form and function, installing in the same location and connecting to the factory harness without modification. Stable switching performance supports dependable operation, accurate operator commands and fewer unplanned interruptions on the yard, dock or warehouse floor.

Installation and Maintenance Tips

• Disconnect the battery and apply lockout/tagout procedures before working on electrical components.
• Match the new switch against the old unit and the 3FD-55-21470 part number before installation.
• Inspect the connector and wiring for corrosion, fraying or heat damage; a new switch will not compensate for a failing harness.
• Seat connectors fully and secure terminals according to the Komatsu service manual for your model.
• Cycle the switch several times and verify operation before returning the truck to service.
• Check electrical connections during scheduled maintenance to catch wear early.
