Frequently Asked Questions
Q: What is the AC 2159-100 contact set?
A: The AC 2159-100 is an electrical contact set used in control circuits for Allis Chalmers electric lift trucks and pallet jacks. Contact sets interrupt or complete electrical circuits during equipment operation and are critical for safe motor control.
Q: Which Allis Chalmers models use the AC 2159-100 contact set?
A: The AC 2159-100 is designed for specific Allis Chalmers electric lift truck and pallet jack models. Confirm your equipment model number before ordering. No cross-reference part numbers are currently available for other manufacturers.
Q: What material are the contacts in the AC 2159-100?
A: Electrical contacts are typically made from silver alloys, copper alloys, or palladium compounds to provide low electrical resistance and resist arcing and oxidation during switching cycles.
Q: When should the AC 2159-100 contact set be replaced?
A: Replace the contact set if the equipment does not respond to control inputs, if there is hesitation or lag when pressing lift or lower buttons, if contacts appear burned or pitted during inspection, or if you observe corrosion buildup on the contact surfaces.
Q: How often should I check the AC 2159-100 for maintenance?
A: Inspect the AC 2159-100 contact set annually or if the equipment exhibits control problems. Clean corrosion from connector pins if visible. If contacts show pitting, burning, or packing of oxidation, replace the entire contact set. Do not attempt to file or clean internal contacts.
