Membrane Switch and Pressure Sensor RFQ

Email the available drawings or start by WeChat or phone. Include the product type, equipment use, mounting conditions and any required interface or inspection criteria. List prototype and expected production quantities separately if known, and say whether the target date is for samples or production. Include a reply contact and mark requirements that still need confirmation.

Yes. Send the information already known and identify the open items. Sample photos, hand-marked dimensions, or available enclosure space can support the first discussion; drawings and further details can follow.

Send drawing files by email, or use WeChat for initial photos and discussion. Identify the project, part number, revision, and date. Confirm a suitable transfer method with the team when files are large or need restricted access.

Tell the team the document name, product type, project stage, and intended use by email or WeChat. Confirm the applicable scope and revision before use. The general project input checklist is also available as a direct TXT download.

Give the estimated annual quantity for each part number, the expected first order quantity if known, and a likely range for later orders. Mark which quantities and delivery dates are estimates. Ask for unit prices at those order sizes, the minimum order quantity, and lead time for each order. When comparing quotes, check whether a price depends on a commitment to buy a set quantity over the year.

Label the drawings Option A and Option B, and say that only one will go into production. Use the same quantities and acceptance requirements for both. Mark what changes between options, such as the overlay material or connector, and flag any assumptions that differ. Ask for a separate breakdown of sample costs, tooling, unit prices and lead times for each option. If you plan to sample both, ask which tools or tests can be shared and what you would pay for before choosing.

Give the required arrival date, destination and minimum quantity for the first fit check. Include the current drawing revision and when you can approve any open items. Ask the supplier to work backward from the arrival date and list the latest approval date, sample completion date, dispatch date and estimated transit time. If a smaller first shipment would help, ask the supplier to quote the quantities, arrival dates and freight for each shipment separately.

Yes. Send the board drawing or a photo showing where the membrane switch tail must reach. If known, include the pin count, pitch, contact side and available clearance. Mark the connector part number as pending. Ask whether the quote covers the switch and tail only or also includes the connector and its assembly. Once you select the connector, send its part number and drawing so the supplier can check fit, pin assignments and any change to cost or lead time before samples are made.
