Abstract: A process for making thin flexible electroluminescent lamps comprises continuously feeding a flexible strip of transparent insulating material which serves as the carrier for performing various process steps, as well as becoming part of the finished lamp itself. The strip is provided with a thin transparent conductive layer. An epoxy/phosphor mixture is continuously applied to a controlled thickness over the conductive layer and cured in an oven. Another conductive layer is continuously applied over the cured epoxy/phosphor layer on the carrier sheet and dried. In a preferred embodiment, lamp members are severed from the roll, and a narrow groove is made in the last applied conductive layer to divide the conductive layer into two exposed electrode areas to which the lamp terminals are connected. In another embodiment, the conductive layer on the plastic carrier sheet is continuously subdivided by vaporizing the conductive material to form a narrow groove with an electric arc.

Abstract: A rocker switch for actuation from outside the bezel or case of a watertight wristwatch employs a rocker arm making contact with the bezel through its pivot pin and having a stem for contacting internal terminals. The handle of the rocker arm is imbedded in adhesive elastomer which is also adhered to the bezel to provide spring action and a water-resistant seal.
