Frequently Asked Questions
Q: What voltage does the HY 2311178 directional control switch require?
A: The HY 2311178 operates at 24VDC nominal. Do not exceed this voltage. Using incorrect voltage will damage the switch and may create safety hazards in the propulsion system.
Q: What is the contact rating for the HY 2311178?
A: The HY 2311178 has single-pole double-throw contacts rated for 10 amperes at 24VDC. Exceeding this amperage will cause contact degradation and switch failure.
Q: How is the HY 2311178 mounted in the truck?
A: The HY 2311178 mounts via a panel cutout with standard screw terminals for electrical connection. Verify panel opening dimensions and terminal accessibility on your Hyster electric lift truck before ordering.
Q: What materials make up the HY 2311178?
A: The body is constructed from polycarbonate resin for durability and electrical insulation. The contacts are copper alloy, designed for long contact life and low resistance. This material combination provides corrosion resistance for industrial use.
Q: What do the SPDT contacts on the HY 2311178 mean?
A: Single-pole double-throw means the switch controls one circuit with three terminals: common, normally open, and normally closed. This allows directional switching (forward/reverse) in propulsion systems.
Q: Is the HY 2311178 compatible with other lift truck brands?
A: The HY 2311178 is an OEM Hyster part. Do not substitute with switches from other manufacturers without verifying voltage, amperage rating, contact configuration, and mounting dimensions. Incorrect switches can fail or create electrical hazards.
