Frequently Asked Questions
Q: What are the electrical specifications of the CT 972202 key switch?
A: The CT 972202 is a 24VDC rated key-operated switch with 6 circuit terminals and 4 discrete switch positions. The nominal input voltage is 24VDC, suitable for standard electric lift truck systems.
Q: What cross-reference part numbers are equivalent to CT 972202?
A: CT 972202 supersedes Caterpillar part 0972202 and replaces parts 1009544 and 1050579. When ordering replacement parts, use CT 972202 to ensure you receive the current OEM specification.
Q: What materials are used in the CT 972202 key switch construction?
A: The CT 972202 features a die-cast zinc cylinder for structural durability and silver-plated copper contacts for reliable electrical conductivity. The keys are double-sided cut, nickel-plated steel for consistent operation and wear resistance.
Q: Why are silver-plated copper contacts used on the CT 972202?
A: Silver-plating provides superior electrical conductivity and resists oxidation, ensuring reliable contact integrity throughout the switch lifespan. This prevents voltage drop and intermittent electrical faults in lift truck ignition and control circuits.
Q: What is a standard panel mount configuration for the CT 972202?
A: The CT 972202 uses standard panel mount dimensions, allowing it to fit into typical lift truck instrument panel openings. Verify mounting hole spacing and dimensions against your equipment specifications before ordering.
Q: What advantage does a 4-position key switch provide on electric lift trucks?
A: A 4-position key switch allows multiple control functions such as Off, Accessory, Run, and Start operations. The 6 circuit terminals enable connection to different control circuits, providing flexible equipment operation and safety interlocks.
