Frequently Asked Questions
Q: What does the HY 238319 butterfly switch control on a Hyster lift truck?
A: The HY 238319 butterfly switch assembly is the operator control for pump or directional hydraulic functions. It is typically mounted on the truck handle and allows the operator to activate lift, lower, or directional movement with thumb or finger actuation.
Q: Which Hyster electric lift truck models use the HY 238319 switch?
A: The HY 238319 butterfly switch is used on Hyster electric pallet jacks and stacker trucks. Cross-reference your equipment model and serial number with Hyster parts documentation to confirm this is the correct replacement switch.
Q: What voltage is the HY 238319 butterfly switch rated for?
A: The HY 238319 switch is rated for 36V electric lift truck applications. Do not use on 48V or 80V systems without verification as incorrect voltage can cause switch failure or electrical hazards.
Q: When should the HY 238319 butterfly switch be replaced?
A: Replace the switch if functions become intermittent, unresponsive, or stuck. Corrosion, water damage, or mechanical wear reduce contact integrity. A stuck or non-responsive switch creates an unsafe operating condition and must be corrected immediately.

A: The HY 238319 is a complete butterfly switch assembly including the button, electrical contacts, and mounting hardware. No additional components are required for installation.
Q: Can the HY 238319 switch be used as a replacement on different Hyster models?
A: Cross-check the switch connector type and electrical specifications with your equipment wiring diagram. Handle design, voltage rating, and contact configuration may vary across Hyster model generations. Using an incompatible switch can cause equipment malfunction or electrical failure.
