INCREASING YIELD WITH TACTILE BUTTON GAP ADJUSTMENT Russian patent published in 2018 - IPC G06F1/16 

FIELD: computer engineering.

SUBSTANCE: group of inventions relates to computing devices having a switch assembly. Based on failure limits of a gap in the switch assembly during manufacturing, a single size for a shim is calculated. Shim is selectively inserted into the switch assembly based on the gap to maximise the switch assembly yield while minimising cost. In some examples, a bracket is designed for the switch assemblies. Bracket has datum surfaces in three dimensions and a beam tuned to absorb energy during an impact event to prevent switch failure.

EFFECT: ensuring the optimisation of the yield of products with one or more switches assemblies, and improving the impact resistance products without loss of tactile sensation.
