China RoHS certified keypad Manufacturer, Supplier, Factory

CSI Keyboards uses copper flex circuitry in the majority of our custom keypad designs due to its excellent dielectric strength, thermal stability, chemical resistance and flexibility. Copper flex, also known as Kapton circuits, have become the superior choice over printed silver especially for outdoor applications. A printed silver circuit can be replaced with a copper and polyimide construction with minimal additional cost. Copper flex circuitry construction designs offer a significant advantage over printed silver. Copper Flex membrane switch panels are produced using polyimide (Kapton) as the base material. Copper flex keypad switches are manufactured by laminating a thin sheet of copper to a flexible film substrate. The copper is then chemically etched away, leaving the copper traces. An additional layer of polyimide is laminated to the circuit leaving the gold contacts exposed

Compared with traditional membrane switches by using the PET silver paste printed flex as the circuit layer, the one key FPC membrane switch is made from Polyimide copper etched FPC circuits. Copper flex traces are more durable and stable, which are resistant to high temperatures up to 280°C, the circuit has high precision, output spacing of 0.5mm or others, low electrical resistance value, high conductivity, stable and reliable performance, and one key FPC membrane switch service life longer than normally membrane switch, ability to solder many kinds of components into the switch design.

Find a huge selection of rubber keypad from China at Tiantai Electronics. Rubber keypad common applications of silicone rubber keypads include remote controls for TV, video and HIFI units, electronic toys and games, and industrial control equipment.

Our waterproof non-tactile membrane switches are made from clear PET, offering long-lasting durability. Waterproof non-tactile membrane switches are characterized their customizability according to your requirements, waterproof non-tactile membrane switches very affordable price, and their aesthetic and practical design

Tactile membrane keypads are designed to provide physical, tactile feedback. The response is typically a “snap” or “click” when the switch is pressed. This is usually a function of a dome switch that is selected for the application. The size, force, and snap required to activate the switch can be customized to your specifications. A non-tactile membrane switch has no tactile response that indicates the button has been pressed. Instead, the response is typically indicated through lights, sound, or reading on the instrument display. With a non-tactile membrane switch, the bottom side of the overlay is connected to a conductive pad, or an upper circuit layer is printed with conductive traces. When the overlay is pressed down the conductive traces connect to the lower circuit layer, which sends a signal to a printed circuit board. Non-tactile membrane switches are more resilient than tactile membrane switches and they are completely sheltered from the outside environment. This allows them to be rated for three times as many activations as a tactile membrane switch.
