Logitech PerfectStroke

PerfectStroke is a trademark used by Logitech for some types of scissor switches. Originally, the name was only for a specific type of scissor switch with a key travel of 3.2 mm, whereas most other scissor switches had a key travel of 2 mm or lower.

In recent times the name has been diluted by having been attached onto keyboards with much less key travel.
