Why Engineers Choose ZIRA
Built Around What Procurement Teams Actually Audit
A switch is only as reliable as the process behind it. Each project follows the same engineering, sampling and test discipline, from a 1-piece prototype to repeat volume orders.
Engineering & DFM Support
Our R&D team reviews your stack-up, circuit routing, dome selection and tail design before tooling. This cuts revision rounds and the risk of field failures.
100% Electrical Testing
Every finished switch is tested for continuity, insulation and key function, then visually inspected before packing. Branded-grade films and adhesives keep the quality consistent.
Low-MOQ, Export-Ready
Small OEM batches are welcome. We ship worldwide under FOB, CIF, EXW, CIP, CPT or DDP terms and accept T/T, L/C, D/P, D/A and Western Union payment.

Manufacturing Process
10 Controlled Steps from Raw Film to Tested Switch
Each stage has its own inspection gate, so defects are caught where they start. They are not left to be found at final test or, worse, in your assembly line.
Raw Materials
Incoming PET, PC, adhesives and inks are checked against spec.
Design
Artwork, circuit routing and stack-up are confirmed with the buyer.
Printing Down
Screens are exposed precisely for each color and conductive layer.
Printing
Graphics, silver circuits and dielectric layers are screen printed.
Drying
Controlled curing gives stable ink adhesion and conductivity.
Positioning Hole
Registration holes keep every layer accurately aligned.
Convex Key
Embossing tools form tactile key shapes and locator rims.
Block Terminal
Female, male or ZIF connectors are crimped onto the tail.
Assembly
Overlay, spacer, domes and circuit are laminated together.
Inspection
100% electrical and visual test before packing.

Buyer's Engineering Guide
Choosing the Right Keypad Technology
Use this quick comparison from our engineering team to shortlist a technology before you send drawings. We will confirm the final specification for your environment and duty cycle.
| Criteria | Membrane Switch | Silicone Rubber Keypad | Capacitive ITO Touch |
|---|---|---|---|
| Profile | Very thin, flat or embossed | 3-D keys with longer travel | Flat, glass-like surface |
| Tactile feel | Metal or poly dome snap | Soft, cushioned stroke | None (haptic or buzzer optional) |
| Sealing | Excellent with perimeter seal | Good with integrated gasket | Excellent, no openings |
| Backlighting | LED, light guide film, EL | LED through translucent keys | LED icon illumination |
| Tooling | Low (screens, dies, embossing) | Compression mold required | Low to medium |
| Typical use | Medical, lab, industrial panels | Remotes, handhelds, rugged gear | Appliances, smart-home devices |
Values describe typical construction. Actual cycle life, actuation force and sealing depend on the dome, material and stack-up selected for your project.
Frequently Asked Questions
What is the minimum order quantity?
Many designs can be sampled from 1 piece. Standard production usually starts at 100 pieces. High-volume items such as numeric PET/PC keypads may start at 1,000 pieces.
What do you need to start a custom project?
A dimensioned drawing (DXF, DWG, PDF or AI), the key layout, circuit schematic or pin-out, tail length and connector type, colors (Pantone/RAL), the adhesive or mounting method, and any environmental requirements. A physical sample also works.
Membrane switch or silicone rubber keypad?
Choose a membrane switch for thin, sealed, easy-to-clean panels. Choose silicone for a soft feel and longer key travel. For the best of both, ask about a hybrid silicone-over-membrane design.
How do you control quality?
Each stage, from printing and drying through positioning and embossing to assembly, has its own inspection gate. Every finished part is then 100% electrically tested and visually inspected.
Which payment and delivery terms do you accept?
We accept T/T, L/C, D/P, D/A and Western Union, in USD, EUR, HKD or CNY. Delivery terms are FOB, CIF, EXW, CIP, CPT, DDP or express.
