Abstract

A knob positioning structure comprises a rotary switch shaft, to which a knob is mounted, the rotary switch being mounted in a depression in an enclosure, within which are formed detent points. A threaded hole is formed in the end of the shaft onto which the knob is to be mounted, and outer serrations are formed around the end of the shaft. The knob has a knob mounting screw hole through which a knob mounting screw can be passed, a knob stopper which mates with a detent point in the depression of the enclosure, and inner serrations, which mate with the outer serrations of the shaft. The knob is mounted to the shaft by inserting a knob mounting screw, via a spring, through the knob mounting screw hole and into the threaded hole in the shaft, enabling a sliding motion between the knob and the shaft in the direction of the shaft axis.

Dependent claims

A knob positioning structure comprising:

a shaft of a rotary switch, onto the end of which are formed outer serrations, and in the end face of which is formed a threaded hole;
an enclosure, into which is formed a depression into which the rotary switch is mounted, detent points being formed on an inner surface thereof;
a knob for operating the rotary switch, said knob having a knob stopper which selects one of said detent points, and inner serrations that mate with the outer serrations of said shaft, these being formed on an inner surface thereof, and having formed in the top part thereof a knob mounting screw hole;
a spring;
and
a knob mounting screw;
wherein said knob mounting screw is passed through said knob mounting screw hole via said spring and is screwed into said threaded hole of said shaft, thereby mounting said knob to said shaft so as to enable mutual sliding therebetween in the axial direction.
