First Claim
Patent Images
1. An elastomeric dome for use with a key, the elastomeric dome comprising:
- a lower portion;
an upper portion; and
a wall that spans from the lower portion to the upper portion, each of the wall, the lower portion, and the upper portion comprising;
a physical property, and the elastomeric dome being tuned to provide predefined tactile feedback over a predetermined travel amount of the key based on a predefined ratio between one of the physical properties and another one of the physical properties.
