Frequently Asked Questions
Q: What is the voltage and current rating for the SY31819 micro-switch?
A: The SY31819 is rated 12A at 125/250VAC, providing SPDT (single-pole, double-throw) switching function. It operates across both 125VAC and 250VAC circuits, making it compatible with standard electric lift truck control systems. Verify your circuit voltage before installation.
Q: What equipment types use the SY31819 micro-switch?
A: The SY31819 is designed for electric pallet jacks, electric hand trucks, and powered stackers from Crown, Toyota, Raymond, and Jungheinrich. It performs limit-switch and safety-circuit functions in lift control assemblies.
Q: What are the physical and operating specifications of the SY31819?
A: The SY31819 has a phenolic resin housing with snap-action lever actuator. Operating force is 1.2 N and release force is 0.25 N. Terminals are #4-40 UNF screw terminals. Electrical life is rated at 100,000 operations under specified load conditions.
Q: What materials and contacts does the SY31819 use?
A: The SY31819 features a phenolic resin housing with silver alloy contacts for reliable current switching. Silver alloy contacts provide stable contact resistance and minimal wear across 100,000+ operating cycles.
Q: How long is the typical lifespan of the SY31819 in lift truck service?
A: The SY31819 has a rated electrical life of 100,000 operations. In typical electric lift truck use, this translates to 3 to 5 years of service. Failure symptoms include erratic limit-switch behavior or complete loss of contact continuity.
Q: Does the SY31819 have cross-reference part numbers?
A: The SY31819 may have equivalents from OEM suppliers. To find exact cross-references, provide your lift truck model and serial number. Our parts team can verify compatibility and identify alternative part numbers for your equipment.
