Frequently Asked Questions
Q: What does the KO 34B-55-23610 directional control switch do?
A: The KO 34B-55-23610 is a Single Pole Double Throw (SPDT) micro switch used for directional control in Komatsu electric lift trucks. It routes voltage to forward or reverse motor circuits, enabling mast up-down or travel direction selection depending on circuit integration.
Q: What equipment is the KO 34B-55-23610 compatible with?
A: The KO 34B-55-23610 fits Komatsu electric lift trucks using 34B-series and 3BA-series control architectures. Cross-references include 34B-57-23610, 3BA-57-23610, and multiple legacy part numbers (LP 393-2142, LP 393-4172, PM 49965-00, TO 0015949, TO 0060302, TO 0300905). Verify your equipment control schematic before ordering.
Q: What is the electrical rating of the KO 34B-55-23610?
A: The KO 34B-55-23610 is rated for 24VDC nominal operation. As a panel-mount micro switch, it handles switching for low-amperage control circuits. Do not exceed rated voltage or current specifications.
Q: Why does the KO 34B-55-23610 have high cycle count rating?
A: The switch is designed for high cycle count operation because directional control switches experience frequent activation during normal truck operation. This rated durability extends service life compared to general-purpose switches in this application.
Q: What symptoms indicate the KO 34B-55-23610 needs replacement?
A: Replace the switch if the truck will not respond to directional inputs, if mast or travel function is stuck in one direction, if the switch feels loose in its mounting, or if contact corrosion is visible at the terminals. Testing with a multimeter should show continuity changes as the lever actuates.
