ABSTRACT:
A keyboard includes a keyboard base, a membrane circuit substrate, and a press key set having a plurality of press keys. Each of the press keys includes: a keycap, a linkage assembly including intersecting first and second link levers, and a first pivot mechanism to interconnect pivotally the first and second link levers, and an elastic element. The first pivot mechanism includes: a female element having a first opening formed in one of upper and lower surfaces of the first link lever; and a flexible male element outwardly protruding from a lateral surface of the second link lever. The male and female elements are configured such that after the male element is elastically deformed to be pressed into the female element via the first opening, the male element is restored to its original form to be limited in the female element.
