A wireless dongle includes a shell having a base board of which an appropriate portion is made of elastic materials to be acted as a switch section, a printed circuit board mounted in the shell and spaced from the base board of the shell, and an elastic member made of elastic materials. The printed circuit board defines a contact area facing to the switch section of the shell. The elastic member is mounted between the switch section of the shell and the contact area of the printed circuit board, and further spaced from the contact area. The elastic member can be elastically pressed to contact the contact area of the printed circuit board by means of pressing the switch section of the shell against the elastic member so as to trigger an electrical signal.
