CONTACTOR (24 VOLT)
Frequently Asked Questions
Q: What voltage and lift truck models does the SW200-473 contactor support?
A: The SW200-473 is a 24-volt DC contactor designed for electric lift trucks including Crown, Toyota, Raymond, Yale, Hyster, Linde, and other OEM brands with 24V electrical systems. It controls the mast motor lift and lower circuits. Verify your truck voltage and original contactor SKU from the service manual or controller nameplate before ordering.
Q: What causes a contactor to fail prematurely?
A: Contactors fail prematurely due to excessive arcing (caused by loose connections or high inrush current), moisture or contamination, incorrect voltage supply, or use of an incompatible SKU with wrong coil resistance. Heavy-duty environments with constant cycling accelerate wear. Burnt contact surfaces, corrosion, and welded contacts are signs of degradation requiring replacement.
Q: How many questions and answers should be in a contactor FAQ?
A: A comprehensive contactor FAQ should cover voltage ratings, compatibility and fitment across OEM brands, failure symptoms and diagnosis, expected lifespan, material properties, cross-reference part numbers, and when replacement is needed. This ensures technicians and parts buyers can make informed decisions on fitment and troubleshooting.
Q: Is the SW200-473 equivalent to other OEM contactors, and how do I confirm?
A: The SW200-473 may have OEM equivalents across different manufacturers. To confirm, provide your lift truck model, year, and the original contactor part number from your truck documentation or service manual. We will cross-reference the part to verify compatibility. Using the exact OEM-equivalent SKU ensures correct solenoid engagement and motor control.
Q: What inspection points indicate a contactor needs replacement?
A: Replace the contactor if you observe severe arcing damage, pitted or melted contact surfaces, coil overheating or burn marks, intermittent clicks without motor engagement, or complete motor shutdown despite good battery voltage. Visible corrosion inside the housing or a burnt smell are also indicators. Preventive replacement in heavy-use environments extends truck reliability.
