Editing Topre switch (section)

==Categorisation==
Because the Topre switch utilizes a rubber dome, there is ongoing disagreement in the keyboard community over whether it should be considered "mechanical" or even "semi-mechanical". Some of this controversy comes from disagreement over whether this categorisation should be determined by its construction (the inclusion of a dome as well as a spring) or by some of its properties that distinguish it from conventional rubber-dome keyboards (crisp, light feel and mid-stroke actuation point).

The switch's dome does provide most of its resistance and all of its tactile feel; but unlike conventional rubber-dome keyboards, the Topre's dome does not provide any "mushy" resistance near the bottom of the stroke. Its conical spring provides only around 5 cN of actuation force and is therefore critical only for sensing keypresses.
