Abstract
Backlighting from a circuit board mounted below a panel display is prevented from seeping around the edges of control actuators which rely on the backlighting to illuminate legends on the face of the actuators. A continuous frame and a layer of foam are disposed about the periphery of the actuators for blocking the seepage of backlighting and half bearings are fixedly attached to the actuators in a manner permitting rotation of the actuators within openings in an escutcheon plate even though the frame is attached to the periphery of the actuators.
