Case Study

Prototype Process Of Custom Membrane Keypad

This case study highlights the successful outcomes achieved through effective collaboration and expertise.

A Custom Membrane Keypad, it has 4 buttons totally, its graphic overlays is black, the 4 membrane buttons are embossing and blue, each switch button is printed with icon "1", "2", "3", "4". In addition, there is a long tail located at the center of the keypad, this kit looks like letter "T".


Case Study Background

LID, a renowned manufacturer of membrane switch and user interface solutions, we were approached by Germany company, a consumer electronics company, to develop custom membrane keypad for their new product line. The customer required high-quality, visually appealing overlays that would enhance the user experience and align with their brand identity.


Customer Requirements

Design and Aesthetics

The customer sought a visually appealing membrane switch that would reflect their brand identity and provide an engaging user interface for their products.
