Embodiment Construction
[0052] Hereinafter, the best embodiment of the variable resistor with switch for implementing the present invention will be described based on the drawings.
[0053] [Basic structure of this embodiment]
[0054] figure 1 Is an exploded perspective view showing an embodiment of the variable resistor with switch of the present invention; figure 2 It is a side sectional view of this embodiment.
[0055] Such as figure 1 , As shown in 2, this embodiment is provided with a shaft holder 51 and a rotating shaft 52. The shaft holder 51, for example, has a first mounting hole 51a and a second mounting hole 51b at the corners of the diagonal line and serves as The central part has a fixed part forming a circular shaft hole 51c and a sleeve part 51f; the rotating shaft 52, the shaft part has a non-circular cross section, that is, an elliptical engagement part 52a, and a small diameter part near the front end 52b, and inserted into the shaft hole 51c of the shaft base 51.
