Frequently Asked Questions
Q: What is the YL 519739835 moving contact assembly used for?
A: The YL 519739835 is a moving contact assembly that works in combination with fixed contacts to switch power in Yale electric lift truck control systems. It physically moves to engage and disengage the electrical circuit during truck operation.
Q: What Yale lift truck models use the YL 519739835?
A: The YL 519739835 is an OEM Yale part designed for electric pallet jacks and lift trucks. Verify your specific model, production year, and serial number to confirm this assembly is the correct replacement.
Q: How does the YL 519739835 differ from a fixed contact?
A: The moving contact assembly in the YL 519739835 is mechanically driven and engages a fixed contact to complete or break the circuit. The fixed contact remains stationary, while the moving contact provides the switching action controlled by the solenoid or contactor.
Q: What causes a YL 519739835 moving contact to wear out?
A: Moving contacts wear through repeated engagement and disengagement cycles, corrosion from moisture, arcing during switching, and high current loads. If the truck exhibits slow response or intermittent power, the moving contact assembly may require inspection or replacement.
