An object of the invention is to provide a illuminated switching device comprising a small number of components and capable of giving stabilized illumination to a translucent portion of a knob. For this purpose, the illuminated switching device of the present invention has a switch section including a case and a switch terminal protruding out of the case, a printed-circuit board to which the switch terminal is connected, and a lamp having a pair of lamp terminals connected with the printed-circuit board. The lamp terminals are retained and supported on the case.

Illuminated switching device for stabilized illumination to translucent portion of knob

In a connection structure of a flat cable to terminals of the present invention, the conductors held by the back film of the flat cable are ultrasonic welded to the terminals of an external part. In this arrangement, even if the conductors are formed to a very thin thickness, since they are neither twisted nor separated from each other, solid-state welding can be made to target positions.

Connection structure of flat cable to terminals

A connecting structure between a flat cable and terminals is disclosed. In the structure, projections are formed on each of a plurality of terminals provided on a lead block, the terminals and a plurality of conductors of a flat cable are overlapped on an anvil of an ultrasonic welding apparatus, and ultrasonic vibrations are applied to overlapping portions of the terminals and the conductors while being pressurized by a horn, whereby solid-phase welding is caused between the projections of the terminals and the conductors, and a plurality of terminal and conductor pairs are simultaneously ultrasonically welded.
