Abstract
A composite switch lever 2 for mounting on the steering column of an automobile is provided with a rotary light switch knob 25 for switching a light switch 24 and a rotary fog switch knob 28 for driving a fog light intermittence switch 29. The switch knobs 25, 28 are rotatably mounted on a lever shaft 13 and an outer cylindrical shaft 14. The switch knobs 25, 28 are coupled with each other through a related operation mechanism (A) composed of a connecting projection 32 and an interfering hole 33 for mechanically coupling the switch knobs 25, 28 with a predetermined idle angle. The composite switch lever 2 prevents a situation where a driver forgets to switch off lights upon getting out of the automobile or turning on a small light. The composite switch lever 2 also makes it possible to reduce the volume of wiring harness between plural switches and lights.
