Editing Tactility (section)

==Overview==
In a tactile switch, the operator feels a distinct change in resistance during the keystroke. In most cases, this results in a rise in resistance followed by a drop in resistance, after which resistance resumes rising. This can be seen in the following animation:

The majority of keyboards sold in the world today are [[rubber dome over membrane]], which is a tactile design.

The following graph depicts a force curve of one type of tactile switch. The peak in the curve at B is the '''tactile peak''': this is a point in the keystroke where the resistance (force) has reached a maximum, after which the force level drops off readily. The sudden drop in resistance from the switch compared with the force still being exerted on the switch typically causes it to immediately bottom out.
