ABSTRACT:
In a vehicle, an air conditioning control with electrical circuit means for carrying substantial current between selective switches located at one part of the assembly where accessible to a vehicle occupant and terminals located at an opposite part adapted to connect to a wiring harness to feed remotely located air conditioning components. The control assembly includes a base member which supports selective controls or switches with a face panel identifying the switches and a circuit carrying sub-assembly including a molded plastic circuit frame which operatively engages the base member in mating face to face contact. The sub-assembly frame supports metal circuit elements in the form of side-by-side terminal strips with a plurality of removable integral connector strips therebetween. The frame further has channel means molded into its surface which mates with the base member. The channels conform to the configuration of the metal circuit elements so that the surfaces of the frame and the circuit elements are substantially co-planar. The co-planar circuit elements and frame mate with or engage a surface of the base member to thereby capture the circuit elements therebetween in good heat transfer contact with both. Further, the framing member includes access means to permit removal of the connector strips between the circuit elements subsequent to mating the base and the frame.
