Frequently Asked Questions
Q: What is the primary function of the YL 620287100 micro switch in Yale lift trucks?
A: The YL 620287100 is an OEM micro switch used for electrical position sensing and actuation control in Yale electric lift truck controller assemblies. It detects lever or hydraulic system positions and sends signals to enable or disable hydraulic functions, operating as a snap-action momentary contact switch with SPDT configuration.
Q: How is YL 620287100 related to YL 6202871?
A: The YL 620287100 and YL 6202871 are equivalent OEM micro switches used interchangeably across Yale electric lift truck models. Both have identical snap-action SPDT functionality. The different part numbering reflects Yale part catalog conventions, but they provide the same electrical performance in control lever and hydraulic assembly applications.
Q: What happens when the YL 620287100 micro switch becomes defective?
A: A defective YL 620287100 switch causes loss of control signal to the hydraulic system, resulting in non-responsive control levers, intermittent function actuation, or continuous activation of a single function. Symptoms typically include inability to raise or lower the mast, stall on directional control, or erratic hydraulic response.
Q: What is the expected replacement interval for YL 620287100?
A: The YL 620287100 micro switch typically remains serviceable for 3 to 7 years in normal material handling duty cycles, depending on frequency of control lever actuation. Environmental factors such as moisture, temperature extremes, or vibration can shorten lifespan. Plan replacement as preventive maintenance every 5 years for high-utilization trucks.
Q: What part numbers can be used as replacements for YL 620287100?
A: Direct replacements for YL 620287100 include YL 6202871, YT 6202871, YT 620287100, and cross-reference 620287100. All provide identical snap-action micro switch functionality. When ordering, specify your truck model and serial number to ensure the correct switch variant, as some trucks may use the -00 or -01 configuration variants.
