Allis-Chalmers TLS Load Tap Changer Contacts

The Allis-Chalmers TLS is a load tap changer found across the utility transformer fleet, and its switching contacts are the primary wear item. The original line is largely out of production, so replacements come from a shop that still makes them. Southern Switch machines and reverse-engineers the full Allis-Chalmers TLS contact set in-house in Palm Harbor, Florida, to the original dimensional specification, including complete contact kits, reversing switch contacts, collector rings, contact fingers. Refurbish your worn contacts or order OEM-spec replacements; lead time is confirmed at quote and material certifications are available.

How we supply them

Refurbished, reverse-engineered, or new.

Send us your worn TLS contacts and we refurbish them where the base material is sound. Where it is not, we machine new OEM-spec replacements, and where the OEM part is long gone we reverse-engineer it from a sample, a drawing, or a model number. That is the difference from a catalog seller: we are the shop making the part. Full LTC rebuild service is available when the whole tap changer needs work.

Common questions

Allis-Chalmers TLS questions.

Are Allis-Chalmers TLS LTC contacts still available?

Yes. The original Allis-Chalmers line is largely out of production, so replacements come from a shop that still makes them. Southern Switch machines and, where the part is obsolete, reverse-engineers the full Allis-Chalmers TLS contact set in-house in Palm Harbor, FL, to the original dimensional specification.

Can you refurbish my existing TLS contacts, or only supply new?

Both. We refurbish customer-supplied Allis-Chalmers TLS contacts where the base material is sound, and machine new OEM-spec replacements where it is not. Material certifications are available on request.

How fast can you supply TLS contacts?

Lead time is confirmed at quote and depends on current material availability. In-stock items ship quickly; reverse-engineered first runs take longer.
