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.
