MICRO-SWITCH
Frequently Asked Questions
Q: What is the MS-78 micro-switch designed for?
A: The MS-78 is a control circuit micro-switch for electric lift trucks and pallet jacks. It serves as a safety or operational sensor to manage circuit continuity based on mechanical position, lift height, or pressure thresholds.
Q: Which electric lift truck brands use the MS-78?
A: The MS-78 is compatible with electric pallet jacks and lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other major manufacturers. Verify your specific model number and voltage rating to ensure proper fitment.
Q: What is the expected service life of the MS-78?
A: Micro-switches typically last 2 to 5 years in normal warehouse operation. Life expectancy depends on cycle frequency, environmental exposure, and mechanical stress. High-cycle applications or harsh conditions may reduce lifespan.
Q: What indicates the MS-78 micro-switch is failing?
A: Failure symptoms include loss of control response to operator input, intermittent electrical function, inability to raise or lower the lift mechanism, or continuous operation without stopping. Multimeter testing confirms loss of continuity.
Q: How can environmental conditions affect MS-78 performance?
A: Moisture, salt spray, freezing temperatures, and contamination from dust or chemicals degrade micro-switch contacts and housing seals. Wet or cold storage environments accelerate corrosion and contact oxidation. Dry, clean conditions maximize lifespan.
