Identify the reference
Folangsi lists this item as a combination switch under its old catalogue code LB04-050-0377A.
Confirm the version
The old catalogue code is not independently verified as a manufacturer part number. Confirm function, label, electrical rating, plugs, mounting and truck identity.
Prepare a useful purchase request
Provide the complete product or truck identification, quantity, application and delivery destination. Include clear photographs of the existing label and connections where relevant. Ask the supplier to identify the exact item, documentation, condition, included scope, lead time and warranty in its written response.
Compare evidence before deciding
Catalogue descriptions are attributed to the supplier. The code alone does not verify origin, current inventory, certification, performance or compatibility. Compare the dated supplier offer with the actual machine documentation and resolve any discrepancy before ordering.
