Editing Ergonomic keyboard (section)

===Light key switches===
Use of lighter key switches could reduce finger strain, but on the other hand a key that is too light would more easily be pressed by mistake. Some keyboards such as the [[Key Tronic#ErgoForce|Key Tronic ErgoForce]] and some variations of the [[Topre Realforce]] have ''variable weighted'' keys, with the key [[weight]] for each key being adapted to the strength of that finger.

If the user can't tell where actuation happens, that could also lead to finger strain. Therefore key ''feedback'' is often also considered an ergonomic aspect. Feedback could be in form of [[Force#Tactile|tactile feel]] and/or a click sound, while many users would be content with consistent key feel or a distinct [[bottoming out]] after actuation.
The [[Kinesis Contoured]] has a built-in electronic speaker for keyboard click, which can be turned off.
