CONTACTOR (24 VOLT)
Frequently Asked Questions
Q: What is the SW200-359 contactor rated for, and which lift trucks use this part?
A: The SW200-359 is a 24-volt contactor used in electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM brands with 24V systems. It switches motor current for mast lift and lower functions. Confirm your truck voltage specification and relay part number from the service manual before ordering.
Q: What is the difference between the SW200-359 and other 24-volt contactors like the SW200-281?
A: Different contactor SKUs are optimized for specific OEM applications and internal specifications. While both are 24-volt units, they may differ in coil resistance, contact material, mounting configuration, or amperage rating. Using the exact SKU matched to your truck model ensures correct solenoid pull-in voltage and contact durability. Mixing SKUs can cause erratic operation or premature failure.
Q: How do I diagnose a faulty contactor on my lift truck?
A: Test the contactor by listening for a loud click when the lift control is activated. If there is no click and no motor response, the solenoid coil may be open or the 24V supply dead. If the click occurs but the motor does not run, contacts may be welded shut or pitted. A multimeter can verify continuity across the coil and contacts. Burned contact surfaces require replacement.
Q: Is preventive maintenance needed on contactors?
A: Contactors do not require periodic maintenance but should be inspected annually in heavy-use environments. Check for carbon dust, corrosion, or visible arcing damage inside the housing. If contacts show significant pitting or discoloration, replacement before failure is recommended. Contamination from dust or moisture accelerates contact deterioration.
Q: What specifications should I verify before ordering the SW200-359?
A: Before ordering, confirm your truck operates at 24 volts DC, identify the original contactor part number from your truck documentation or parts diagram, and verify the motor amperage rating matches this contactor design. Contact us with your lift truck model, serial number, and current part number for rapid cross-reference verification.
