Abstract (en)
A switch assembly for use in a notebook computer keyboard has a key (1) comprising a plunger (11) which has a detention means (111) directly resting on a mounting means (121) of an elastic body (12) inside a housing (13) of the switch assembly. Due to the design of the plunger of the present invention there is no structural interference involved when the key is depressed. The diameter of the elastic body is made large. Furthermore, the contact diameter of the plunger and the mounting means is large so that high stability is achieved when the key is depressed downwardly. <IMAGE>
