Abstract
A toggle switch has a light emitting diode element (LED) attached to the top end of a knob. The other end of the knob is attached to a rockable member which is supported by a case to be turnable within a predetermined angle. Two lead wires of the LED are inserted, respectively, into two holes in an insulating plastic spring holder fitted in the knob, through one-end openings of the two holes which extend along the axial direction of the spring holder and open at the other end of the knob. A conductive metal coil spring is contained in each hole and each lead wire is inserted into and electrically contacted with its corresponding coil spring at many places. The other opening of the hole is located in the vicinity of the rocking center of the rockable member, at which area is also located a pair of conductive metal terminals for power supply. A conductive metal connecting bar is attached to the end of each coil spring contained in each said hole, and is spring-biased to bear against its corresponding terminal, the coil spring and terminal being securely electrically connected with each other by means of the bar.
