LIGHTING STRUCTURE OF BUTTON

PROBLEM TO BE SOLVED: To provide lighting structure of a seesaw button with a means of preventing leakage of illuminating light in the button without increasing number of components. SOLUTION: This button is and a seesaw button that actuates plural switches selectively by pushdown action of a single button. The button comprises a top part having letters and marks on it, switch pushing parts which actuate switches, seesaw supports for pushing operation, a part of preventing the leakage of the light set in lower end of the button and light-emitting diodes set under the back of the top part in order to illuminate the top part. Furthermore, it is characterized in that the part of preventing the leakage of the light is set so as to enclose the light-emitting diodes and extend below the diodes, therefore the reflected light that should leak from below the seesaw button is shield by the part of preventing the leakage of the light when the diodes are turn on.
