Colour is a visible part of a switch and socket specification, but a series-level colour chart does not mean every function is available in every finish. Confirm colour availability against the exact model codes in the project schedule.
Separate finish from function
Prepare the model list, then record the required finish next to each item. Ask the supplier to confirm available finishes by item code rather than relying on a series photograph. This helps identify missing combinations before quotation or sampling.
Review the range as a set
When switches, sockets, data outlets and accessories sit together, approve them as a coordinated group. Request samples or current images for the exact finish and compare them under lighting similar to the final space. A physical sample is more reliable than a screen image for final colour approval.
Check production and packing details
Confirm whether each finish has different order or lead-time conditions, and how it is identified on carton and item labels. Keep finish names, codes and approved samples linked in the order record. Review any proposed substitution against the approved sample.
Approval checklist
- Record finish by exact model code.
- Confirm which functions are available in that finish.
- Approve a labelled sample under representative lighting.
- Check colour names on the quotation and packing list.
- Keep an approved reference for repeat orders.
OUBEN’s catalogue shows colour variants for selected products. Confirm availability item by item; colour options should not be counted as separate product models or assumed across the full catalogue.
