ABSTRACT:
A metal dome switch includes a touch element protruding from a center of the metal dome switch, a connecting element integrally extended from a periphery of the touch element and a mountable surface integrally formed on the touch element. Since the touch element, the connecting element and the mountable surface are integrally formed; the manufacture cost of the metal dome switch can be reduced.
