Illumination and visual indicator
Equipment including an assembly structure defining an interior, and including a panel and a viewing window in the panel. An electro-mechanical operating device is located within the interior. The electro-mechanical operating device has at least two visually-distinguishable operational states, and is positioned such that the operational state of the electro-mechanical operating device can be visually observed through the viewing window. An illumination device within the interior emits light of at least two different colors corresponding to the at least two visually-distinguishable operational states of the electro-mechanical operating device. Electrical circuitry includes a switch for sensing the operational state of the electro-mechanical operating device and connected for controlling the illumination device.
