Frequently Asked Questions
Q: What is the DW 908450 switch and what does it control?
A: The DW 908450 is a directional control switch used in electric lift truck drive and control systems. It is a momentary-contact DPDT (double-pole double-throw) switch rated at 48 volts DC, 10 amperes. It controls the direction of motor or hydraulic flow in lift, lower, or travel functions. Cross-references include HY 2304182, HY 2311178, HY 3016151, HY 519515302, SW 1039, and SW 151FA.
Q: What equipment models use the DW 908450 directional switch?
A: The DW 908450 is compatible with select Daewoo, Hyster, Yale, Caterpillar, and Toyota electric lift trucks that use 48 VDC control systems. It replaces HY 2304182 and supersedes SW 1039. Cross-reference part numbers HY 2311178, HY 3016151, HY 519515302, and SW 151FA are equivalent. Verify your equipment voltage and switch cavity mounting before ordering.
Q: What are the physical dimensions and mounting specifications for the DW 908450?
A: The switch has two-hole mounting with 1.25-inch hole spacing and an overall enclosure size of 3.25 inches by 2.00 inches by 1.50 inches. It uses screw clamp terminals for wire connections. An impact-resistant polymer body protects internal contacts from mechanical shock and vibration.
Q: What is the electrical rating and contact material of the DW 908450?
A: The DW 908450 is rated for 48 volts DC at 10 amperes maximum load. Contacts are silver alloy, which resists corrosion and provides consistent electrical conductivity. The switch has a 250,000-cycle mechanical life rating and 50,000-cycle electrical life rating, meaning it is designed for continuous duty in lift truck operation.
Q: How do I know if the DW 908450 needs replacement?
A: Signs of switch wear include sluggish response to control lever movement, intermittent activation, or failure to maintain motor direction without continuous pressure on the lever. If the switch does not click firmly or if the equipment drifts or moves unexpectedly, the switch likely requires replacement. A worn switch is a safety risk and should not be repaired.
