LED Indicator Embossing Tactile FPC Circuit Membrane Keypad

LUPHITOUCH Customizes LED Indicator Embossing Tactile FPC Circuit Membrane Keypad VTMS00315

Membrane switch is a kind of widely applied keypad for human interface of machine, instrument, medical device, household appliances etc. The buttons can be Polydome or tactile metal domes. The membrane switch also can be assembled indicator LEDs on silvr printed PET circuit or copper flex FPC circuit or rigid PCB circuit board. On the graphic overlay can print different colors by screen printing or digital printing. The membrane keypad can give the end user a very direct and friendly interface and convenient operation method.

PRODUCTION DESCRIPTION

> Construction:

A membrane switch typically has 6 or more or less layers. The top layer of a membrane switch is the graphic overlay interface between the user and the machine. The other critical layer is a the circuit layer. It can also be PET, FPC or PCB. All the layers are normally assembled using pressure-sensitive adhesives. Contact between two traces can be made through a printed shorting pad or through a metal dome that stands on legs.

> 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.
