Frequently Asked Questions
Q: What is the current and voltage rating for SKU 319033 micro-switch?
A: The 319033 micro-switch is rated for 25A maximum at 208-230VAC with SPDT configuration. It also functions in 110VAC circuits. Do not exceed the 25A resistive load rating.
Q: What OEM part numbers does the 319033 cross-reference?
A: The 319033 replaces OEM part numbers 991088, 1258-AA, 991226, and BH-7004-19. Equivalent part numbers include A00242, 80282, 300282, 290037, 1288AA, C-723-20, 0352, 69210023, S707, and 6-0916. Verify compatibility with your specific lift truck model.
Q: What type of actuation does the 319033 have?
A: The 319033 features a heavy-duty plunger actuator with SPDT configuration. It includes threaded brass mounting for secure installation in electric lift truck applications.
Q: Is the 319033 suitable for cold storage or outdoor environments?
A: The 319033 is designed for standard electric lift truck environments. For extended operation in cold storage or wet conditions, inspect contacts regularly for corrosion and moisture accumulation.
Q: How do I identify if my micro-switch is failing?
A: Symptoms of micro-switch failure include loss of electrical continuity, intermittent operation, or contact chatter. Plunger stiction and contact erosion are common failure modes in material handling equipment.
