#174438 - Some switches have very long bounce time
Responding to: ???'s previous message
Some switches can have a very long bounce time - a lot depends on the mechanical design. 11ms is a very short time - you may find that 50ms isn't enough. When you need short latencies or very high key prepetition frequencies, you have to keep an eye on the selected switches.
