Keyboard switch having integral bezel

A keyboard switch assembly of the type comprising a housing having a keyboard face, a plurality of switch sites on the keyboard face, first and second parallel conductor supports which extend parallel to the keyboard face, the supports having spaced-apart first and second opposed surfaces respectively, the first surface having circuit conductors thereon and having a plurality of pairs of spaced-apart switch electrodes, each pair of switch electrodes being in alignment with one of the switch sites, the circuit conductors extending to the switch sites, the second surface having a plurality of commoning conductors thereon, each commoning conductor being opposed to one of the pairs of switch electrodes, the first support being a continuous flexible insulating film so that upon application of a switch closing force to one of the switch sites on the keyboard face, the switch electrodes associated with the switch site are contacted with the associated commoning conductor thereby closing the switch, the switch assembly being characterized in that:

• the second conductor support is firm molded plastic material and has a planar separator surface which is opposed to, and substantially against, the first surface of the first support, the separator surface having recesses therein at the switch sites, the recesses having recess surfaces which are parallel to the first surfaces, the commoning conductors being located on the recess surfaces, the recess surfaces constituting the second surface of the switch assembly,
• the second conductor support having a bezel integrally molded therewith, the bezel surrounding the separator surface, the support surface being sunken in the bezel and the bezel having a boundary surface which extends normally of, and circumscribes, the support surface,
• the bezel having a plurality of bezel slots extending into the boundary surface, the first support having flexible retaining extensions which extend into the bezel slots for retaining the first support against the separator surface, and
• the first support has a flexible tail extending therefrom, at least some of the circuit conductors extending onto the tail, the bezel having a tail slot therein extending from the separator surface, the tail extending through the tail slot.
