What Is Snap Ratio in Silicone Rubber Keypads?
Silicone rubber keypads often produce tactile feedback in response to key presses. When you press a key, you'll not only hear it; you'll feel it as well. Some silicone rubber keypads, however, produce stronger tactile feedback than others. The level of tactile feedback produced by a silicone rubber keypad is measured in snap ratio.

Overview of Snap Ratio
Snap ratio refers to the level of tactile feedback produced by a keypad, including silicone rubber keypads. The higher the snap ratio, the greater the tactile feedback.
Although there are exceptions, most silicone rubber keypads produce at least some tactile feedback. They are designed with a central switch that's supported by elastic silicone rubber webbing material. The webbing material wraps around the central switch. Pressing the key will push the top conductive contact into the bottom conductive contact, thereby deforming the webbing material. When you release your finger from the switch, the webbing material will spring or "snap" back up. This action creates tactile feedback that you can feel.
