Contactor, 24 Volt
Frequently Asked Questions
Q: What is the voltage specification for the AL SW200-420 contactor?
A: The AL SW200-420 is a 24-volt contactor designed for electric lift truck control circuits. The 24-volt specification matches standard material handling equipment from Crown, Toyota, Raymond, Hyster, and similar manufacturers. Verify your truck nameplate voltage before ordering.
Q: What lift truck brands and models use the AL SW200-420?
A: The AL SW200-420 is compatible with specific electric pallet jack and lift truck models from brands including Crown, Toyota, Raymond, Jungheinrich, Linde, and Yale. Compatibility varies by model series and production year. Cross-reference your equipment serial number and schematic to confirm the correct part.
Q: What happens if a contactor fails on my lift truck?
A: A failed contactor interrupts power to its associated circuit, typically causing complete loss of drive, lift, steer, or braking function. The truck becomes unsafe or immobile depending on which circuit is affected. Contactors cannot be repaired and must be replaced.
Q: How do I diagnose a bad contactor?
A: First verify the control switch sends a signal. Use a multimeter to test for 24 volts at the contactor coil terminals. If voltage is present but the contactor does not energize, the coil is open. If the coil energizes but the load circuit does not conduct power, the contacts are welded or burned and replacement is required.
Q: What is the typical service life of this contactor?
A: Contactors typically last 3 to 8 years depending on duty cycle, environmental exposure, and electrical load. Heavy usage, frequent start stop cycling, and moisture exposure shorten life. Once failure symptoms appear, do not delay replacement, as continued operation can damage the motor or charger.
Q: Can the AL SW200-420 be swapped with AL SW200-24 or AL SW200-487?
A: No. Each contactor is engineered for a specific truck platform and control circuit. Using the wrong part number creates circuit incompatibilities and equipment faults. Always match the exact SKU from your truck schematic or consult your equipment documentation.
