China membrane keyboard sensor Manufacturer, Supplier, Factory

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.

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.

According to the structure and function of the customer's products, our Push Button Switch Silicone Rubber keypad can customized size, color and different shapes of the keys which require by customer, and provide spraying, laser etching and silk screen printing services.

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

Tiantai electronics custom fpc membrane keyboard will be based on product application, circuit density, conductivity, resistance, whether many electronic components are required, operating environment, customer budget, and whether to pay attention to silver migration. Flexible membrane keyboard assemblies (FPC membrane switch, silver flex membrane switches, and PCB membrane switch). Silver migration usually occurs in Silver Flex Membrane Switches, which is caused by high voltage and humid environments.

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.
