Frequently Asked Questions
Q: What equipment does the 393-2931 micro-switch fit?
A: The 393-2931 micro-switch is designed for electric lift trucks and material handling equipment from Crown, Toyota, Hyster, Raymond, and other OEM manufacturers. Verify dimensions and contact configuration against the original part before ordering.
Q: What is the difference between the 393-2931 and standard switches?
A: Micro-switches are compact switches with high precision and sensitivity. The 393-2931 is typically used in limit circuits, safety interlocks, or operator control applications where precise switching action is required in confined spaces.
Q: What are the electrical specifications for the 393-2931?
A: The 393-2931 specifications include voltage rating, amperage rating, actuator type, and contact configuration. Review equipment schematics or the original part nameplate to confirm these specifications match your application exactly.
Q: How do I diagnose micro-switch failure in the 393-2931?
A: Failure signs include loss of limit function, continuous error conditions, equipment safety interlocks not responding, or mechanical binding of the actuator. If the circuit does not respond after visual inspection and cleaning, replace the micro-switch.
Q: What is the operating lifespan of the 393-2931 micro-switch?
A: Micro-switch lifespan varies based on cycle frequency and environmental exposure. High-cycle applications may show wear within 2-3 years. Clean storage and protection from excessive moisture extend service life.
Q: What cross-reference numbers are available for the 393-2931?
A: Check the original micro-switch in your equipment for OEM part numbers and cross-references. Different manufacturers may use different part numbers for compatible switches. We can help identify equivalents if you provide your equipment model.
