Abstract
In the tactile effect switch and a keyboard using such a switch, the tactile effect is obtained by combining a snap acting switch and the deformation of a stud, axially deformable under compression, which is integrally formed on a membrane made from a resilient material disposed on a support plate and which provides a resilient connection between a key and the switch in the manner of a pusher.
