Embossing in Membrane Switches

To provide tactile feel to a membrane switch or graphic overlay, the material can be embossed to raise the key area. Embossing has really become standard in membrane switch designs. Not only does it give it a better look and feel, but it also allows the user of the end product to find the key and provide tactile confirmation that the button is present even before it’s pressed. 

There are essentially three options when it comes to embossing membrane switches: pillow emboss, rim or perimeter emboss, and LED or Brail emboss.
