    wherein a light pipe member is used to hold the actuators within the escutcheon plate, the light pipe member being of transparent material;

    the improvement comprising;

    (a) means attached to the peripheral edge of the actuators for opposing seepage of backlighting through the apertures of the escutcheon plate and around edges of the actuators; and
