Abstract
Disclosed is a seesaw switch with a light emitting diode element in which a light emitting portion of the light emitting diode element is disposed on the surface of a seesaw button. The base of the light emitting diode element is attached to a holder, lead wires of the element extending along the outer surface of the holder. The holder is received by a receiving portion of a rockable member, which is rockably borne on a case. The rockable member is fitted with a spring-biased rod, which, accompanying the rocking of the rockable member, slides on a movable contact laid on two switching terminals and a common terminal fixed to the bottom portion of the case for seesaw motion. Also fixed to the bottom portion of the case are two terminals for supplying electric power to the light emitting diode element. A spring of electrically conductive metal is inserted in each of these terminals, one end of the spring pressing on each corresponding lead wire on the outer surface of the holder and the other end pressing on each corresponding terminal.
