ABSTRACT In a process of producing a keyboard switch, a continuous track of a metal foil is machined into two metallic terminal components constituting links between two carrier strips. A base housing component is cast from a high temperature resistant material around the terminals and is connected to the carrier strips through two tags protruding outwards from opposite, outer side surfaces of the base housing component. In an inner recess of the base housing component a domed metal disc having an accoustically damping coating on the convex side surface thereof, an elastically compressible rubber component and a push button are arranged. On top of the base housing component, a top housing component preferably made from the same high temperature resistant plastics material is arranged, within the recess of the base housing component, the terminals define electric contacts with which the domed metal disc co-operates. The terminals are separated from the carrier strips and bent into the configuration of pins of an electronic keyboard switch, and the keyboard switch is still connected through the tags to the carrier strips transferred to a test stand, in which the keyboard switch is tested. Provided the keyboard switch is identified as a properly functioning keyboard switch, the tags are separated from the base housing component.
