Each of the rubber contact portions produces a suitable click feeling by a resilient force, produced by elastic deformation of the rubber contact portion, at the time of operating the operating knob (). The rubber contact portion () has overstroke means by which after its conductive piece () contacts the opposing switch contact portion (), a click feeling is not produced until the switching operation of the rubber contact portion () is completed.
