Abstract
A pushbutton of a switch assembly has an improved display system which includes a housing formed of an electrically insulating polymeric material. A solid-state display system is disposed within the housing. The solid-state display system includes an array of light emitting diodes mounted on a circuit board. The circuit board is disposed on a metal heat sink. The heat sink positions the circuit board relative to the display housing and receives heat from the light emitting diodes. In addition, the heat sink forms a portion of a circuit which conducts electrical energy to energize the light emitting diodes.
