Specification:
> Application
Classic applications of membrane switches include consumer electronics like the microwave oven panel, air conditioner control panel, TV remote control etc., machinery, test instrument, meters, medical industry, energy industry, Auto industry, aviation industry, healthcare industry etc. Tactile feedback of keys can be provided by embossing the top PET/PC layer or embedding metal snap domes, polyester domes or forming the graphic layer.
The benefits of membrane switches include flexible, easy of cleaning, sealing ability and low profile.
> Our Services and Advantages:
1) Artwork design and making;
2) Has our own finally assembly factory which can assemble the complicated keypads with plastic, metal, PCB, FPC etc.
3) Design improvement suggestion against the customer’s original design;
4) Experienced workers and engineers;
5) ISO certified factory;
6) Imported material, like the Autotype PET, 3M adhesive, Nicomatic connector etc.
> Membrane Keypad Structure
1) 4 layers structure: Graphic overlay + Spacer + Circuit(can be PET circuit or FPC circuit) + Back Adhesive
2) 6 layers structure: Graphic overlay + Spacer: Dome Retainer + Spacer + Circuit(can be PET circuit or FPC circuit) + Back Adhesive;
3) Other Structure
3.1) Overlay + Rubber Adhesive + Rubber Keypad + Rubber Adhesive + Retainer + Spacer + Circuit + Back Adhesive;
3.2) Overlay + Spacer + Retainer + PCB Circuit;
And also there are many other kinds of structures for the interface keypads structure. It based on customer’s real needs and we can design the suitable and economical structure for our customer’s final application.
