Abstract
A front panel assembly for an electronic instrument having a one-piece key pad with a plurality of protuberances thereon. The protuberances are formed in groups according to function and all protuberances in a group are positioned in proximity to each other. Each group of protuberances has a header protruberance defining the function of the group. Each protrusion, except the header protuberances has a corresponding electrical switching member connectably attached thereto. Each protuberance, except the header protrusions, functions as a key. When a key protuberance is pressed, the corresponding electrical switching member is pressed into operative engagement with a corresponding circuit on the circuit board. An alternate embodiment allows one group of keys to be replaced with a rotary dial without remaking the key pad.
