ABSTRACT:
A switch device suitable for application in a window regulator of an automobile. The switch device is capable of detecting three distinct operations of a knob, and is comprised of: a first operation to one side from a neutral position; a second operation to the opposite side; and a third operation to the first side larger than the first operation. Two switches are provided in correspondence to the respective first and second operations and these switches are provided with contacts which are switched by these three operations. When the third operation is effected, an interlock member transmits this third operation to the second switch, whereby the contacts of both the first and second switches are caused to be switched simultaneously.
