Claim:
A key plunger for a key of an electronic device, comprising: a stalk made of a first material allowing light to pass through; a plinth connected to the top of said stalk; and a body section connected to the top of said plinth, said body section made of a second, material and shaped to fit snugly within an interior of a cap for said key and to extend horizontally about said stalk, wherein said second material is a translucent, light-diffusing material; said first material allows more light to pass therethrough than said second material; either a two-shot moulding process or a welding process is used to form said key plunger; in said key plunger, said second material disperses light from a source located below said body section which enters said body section into a region in said body section immediately over said stalk to brighten a first shadow region associated with said region in said body section; and said transparent material transmits light passing through said stalk from said source to brighten a second shadow region located on a side of said stalk which is opposite to said source.
