Abstract
Depressable key device carrying a contact plate subjected to a magnetic attraction force attracting the key towards its rest position and cooperating with a conductor surface independent of the key to form a mechanical switch closed in the rest position of the key. The contact plate (15) carried by the lower plate (14) of the key comprises a resiliently yieldable tongue (23) ended by a contact stud (22) cooperating with a contact chip (21) of a printed circuit, the tongue (23) being deformed resiliently upon depression of the key to exert on the stud (22) an action which is opposite to the magnetic attraction of the stud by a sheet (17) of magnetic material. Application particularly to keyboards and push-buttons of the type having contacts which are closed in the rest position.
