Frequently Asked Questions
Q: What is the difference between the SW2001-281 and SW200-281 contactor SKUs?
A: The SW2001-281 and SW200-281 are distinct part numbers with different internal specifications or OEM applications. The SW2001-281 is optimized for specific lift truck models or electrical configurations. Always use the exact SKU listed in your truck service manual or original parts diagram. Mixing SKUs will cause solenoid pull-in failures or erratic motor control.
Q: Which electric lift truck models use the SW2001-281 contactor?
A: The SW2001-281 is a 24-volt contactor used in specific electric lift truck models from Crown, Toyota, Raymond, Yale, Hyster, CAT, BT, Mitsubishi, and other OEM manufacturers. To verify fitment, provide your truck model, year, and serial number. We will confirm the correct SKU and availability for rapid order placement.
Q: How do I troubleshoot lift truck motor control issues related to the contactor?
A: First, check that the battery has adequate voltage (typically 24V or higher). Next, listen for a loud click when the lift lever is engaged. If no click occurs, the solenoid coil may be open or the control circuit broken. If the click happens but the motor does not run, the contactor contacts may be welded or pitted. Test with a multimeter to confirm continuity and measure voltage across the motor terminals.
Q: What material grade and contact specifications should I expect in the SW2001-281?
A: The SW2001-281 features high-conductivity silver alloy or similar contacts rated for 24V DC motor switching. The solenoid coil is wound for the exact pull-in voltage of your truck system. The housing is molded plastic or metal with internal spring and mechanical linkage to ensure reliable contact engagement under heavy-duty lift cycles. Specifications are optimized for industrial warehouse environments.
Q: What is the expected lifespan and maintenance requirements for this contactor?
A: The SW2001-281 typically lasts 3 to 8 years depending on duty cycle and environment. Heavy-use warehouses may see earlier failure due to increased arcing and contact wear. No scheduled maintenance is required, but annual visual inspection for carbon buildup or corrosion is recommended. Replace the contactor at first sign of poor lift control or clicking without engagement to avoid motor damage.
