Frequently Asked Questions
Q: What equipment does the SW-1793 switch fit?
A: The SW-1793 is an industrial electric lift truck switch designed for control circuit applications. It is a direct replacement for OEM part numbers HY 800018666, and is cross-compatible with equivalent part numbers LP 393-9905, TY 00591-73980-81, YT 220042503, and YT 800018666 across multiple lift truck brands including Hyster, Toyota, Yale, and Jungheinrich.
Q: What are the key specifications of the SW-1793?
A: The SW-1793 features a maintained ON-OFF function for sustained control circuit operation. It is rated at 24VDC control circuit voltage with silver alloy contacts for reliable electrical conductivity. The robust thermoplastic actuator ensures durability and long service life in industrial material handling environments.
Q: Can I use the SW-1793 as a replacement for other switch part numbers?
A: Yes. The SW-1793 replaces OEM part number HY 800018666 directly and is functionally equivalent to cross-reference part numbers LP 393-9905, TY 00591-73980-81, YT 220042503, and YT 800018666. Verify that your equipment model and control circuit specifications match this switch before ordering.
Q: What do the silver alloy contacts do?
A: The silver alloy contacts provide superior electrical conductivity and resistance to corrosion and oxidation. This ensures consistent, reliable contact closure in the control circuit and extends the switch lifespan compared to standard material contacts. Silver alloy contacts maintain low contact resistance even after thousands of actuation cycles.
Q: What is the maintained ON-OFF function?
A: The maintained ON-OFF function means the switch remains in the selected position after actuation until manually moved to a different position. Unlike momentary switches that require continuous pressure, maintained switches hold their state without ongoing input. This design is common in lift truck control circuits for sustained operations.
