A PCB membrane switch is a type of electrical switches, which is characterized by the use of a printed circuit board. The term “PCB” even refers to “printed circuit board”, which is the primary feature driving this switch's popularity.

As the professional manufacturer, TianTai Electronics would like to provide you high quality FPC circuit push button membrane keypad, which is designed to provide users with a durable and long-life using switch solution that is ideal for a variety of all areas. With its flexible printed circuit (FPC) design, the switch is able to be mounted in tight spaces and can withstand even the toughest conditions.

In the filed of modern electronic components, the gold-plating metal dome membrane switch has emerged as a crucial element, widely used in various electronic devices.

Seit über 25 Jahren entwickeln und fertigen wir kundenspezifische Folientastaturen und Dekorfolien für anspruchsvolle Anwendungen. Ob in der Industrieautomation, der Medizintechnik oder der Automobilindustrie – überall dort, wo Zuverlässigkeit, Widerstandsfähigkeit und präzise Bedienung gefordert sind, kommen unsere maßgeschneiderten Tastaturen zum Einsatz.

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 membrane switch manufacturer. The membrane switch is composed of six layers: Graphic overlay, overlay spacer, dome retainer, circuit spacer, the lower circuit and the back adhesive. The contact of the upper circuit is downward, and it is in contact with the point of the lower circuit. The circuit contact bounces back after releasing, then the circuit is disconnected and the loop triggers a signal.
