LED Membrane Switch non-tactile membrane switch keypad
1. What is membrane keypad?
It is an operating system, which integrates key function, indicator
element, and instrument panel. Also, it’s called touch keyboard,
because the keypad will generate a tactile response in use. It
adopts an integral sealing construction combined with flat and
multi-layers. As we all know, the structure seals tactile membrane
switch, graphic overlay, mark, symbol display, and lining board
together. This membrane switch keyboard is a new type of electronic
component, integration of light, machine, and electricity.
Furthermore, the appearance of this type of keyboard marks a
fundamental change in the appearance and structure of printed
electronic products. This type of switch can replace key buttons of
the regular discrete component part to perform the tasks of the
operating system more reliably.

2. Membrane keypad structure
So which parts does the membrane switches keyboard consist of? They
are not the same as mechanical switches. In general, membrane
switch keypads have six parts. Including graphic overlay, graphic
adhesive, upper circuit layer, adhesive separator, lower circuit
layer, and adhesive bottom layer.
3. Membrane keypad types
Flexible membrane switch, rigid membrane switch, and raised
membrane switch.
