Key switch assembly

A key switch actuator for use with keyboard assemblies including a substrate, said substrate having opposite first and second surfaces with aperture means therein at predetermined locations and said substrate having first and second conductive paths on said first surface, said key switch actuator comprising:

• (a) a base member defining an opening therein with positioning means associated therewith, said base member further including projection means extending therefrom engageable at said aperture means to secure said base member to said substrate;
• (b) contact means having a peripheral and a central portion and further having oppositely extending tabs received in said positioning means for positioning said contact means in said base member in a normally non-actuated position with said peripheral portion of said contact means in electrical contact with said first conductive path and with the said central portion of said contact means being out of electrical contact with said second conductive path;
• (c) key means hingedly secured to said base member and having a first non-actuated position and a second actuated position, said key means including depending striker means cooperable with said contact means to move said contact means into electrical contact with said second conductive path in said actuated position;
• and
• (d) key cap means detachably secured to said key means and wherein said key means and key cap means are in cantilever relationship with said base member.
