ABSTRACT:
Electrical instrument gage that has a pointer indicator member mounted on a rotatable shaft extending from the gage and including an electrically energizable light source mounted on and extending along the pointer portion of the indicator member. The light source is preferably an electroluminescent lamination that contains a pair of flex circuit terminal contacts extending from its base end. The light source is adhesively attached to the pointer portion of the indicator member. The base element of the indicator member contains a socket portion with a cylindrical opening configured to provide a friction fit to the axial shaft extending from the gage. The outer cylindrical surface of the socket contains an electrically conductive area and the gage contains an electrical wiper contact that makes continual electrical interconnection with the conductive portion of the socket over its rotational range. This electrical interconnection provides the power for the light source that is attached to the instrument pointer.
