Gasket seal A gasket seal is used to protect the conductors against humidity and splashes. When humidity seeps into an unprotected membrane switch, migration and oxidation of the conductors can occur. Bolin recommends adding a seal as a precaution if there is humidity or liquid present. EMI / RFI / ESD Shielding EMI : Electro-magnetic interference RFI : Radio frequency interference ESD : Electro-static discharge An aluminum foil shielding is laminated to the circuit to absorb electro-static discharges. The ground can be connected to the switch cable or be separated as a stand-alone cable. If there are transparent windows on your graphic overlay (LCD display for instance), it is possible to use a clear ITO electrical conductive polyester which will provide the same protection as the aluminum shielding.

As the professional manufacture, TianTai Electronics would like to provide you membrane switch for educational toys, which have become part of modern educational toys and has user-friendly and durable way for children to contact with their playthings. These switches are with thin, flexible panels with printed circuitry that respond to pressure. When a child plays with this toys contact membrane switch touch area, it sends an electrical signal to the toy's internal system, triggering sounds, movements, or educational content.

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.

Tiantai Electronics is a leading China pmma overlay for home appliance manufacturer and supplier. PMMA noverlay for home appliance are film sheets that display custom text and designs that are usually placed on the exterior layer of a product. They add a level of professionalism, while also incorporating another layer of protection.

Glass Overlay for Door Lock is durable accessory that improve the security of your home. This product is designed to fit perfectly on most standard door locks, adding an extra layer of protection to your house while complementing your inside design.

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
