Membrane Switch RFQ Checklist
A useful RFQ does not need to be perfect. It needs enough information for the supplier to see the stack risk, cost drivers, and missing decisions.

Engineering reference
Practical decisions
Send drawings in layers when possible
AI, PDF, DXF, STEP, or Gerber files are all helpful if they show cut lines, window areas, key positions, tail exit, connector, and adhesive boundary. A screenshot alone usually creates rework.
Separate must-have from preference
If IP67, glove use, chemical wipe-down, UL material, or a specific connector is mandatory, mark it clearly. If the film, adhesive, or dome force is flexible, say so. That gives engineering room to optimize cost.
Quote sample and production quantities
Sample tooling, screen setup, fixture cost, and batch pricing depend on quantity. A 20-piece pilot and a 10,000-piece annual program should not be quoted with the same assumptions.

FAQ
Questions buyers usually ask
Is this a final engineering specification?
No. It is a practical sourcing guide. Final decisions should be confirmed through drawing review, material samples, and application testing.
Can the checklist reduce sample loops?
Usually yes. It helps buyers send the constraints that often cause rework: tail route, connector, adhesive, environment, life cycle, and sample deadline.
Can this be reviewed by the factory team?
Yes. Send the project details through the RFQ or drawing review page and include any fixed requirements that cannot change.
RFQ support
Send a drawing before the design is locked.
For your membrane switch project, the useful review happens before tail exit, connector, adhesive, and artwork decisions become expensive to change.
