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.

Abstract

The present invention provides a variable resistor with a switch, the click mechanism is constituted to provide a click member 53 and a plate spring 54 for click, a resistor unit is constituted to comprise a resistance board 57k and a first slider including a contact 58a1, a rotary switch is constituted to comprise a second insulating case 59 as a contact board and a second slider including a contact 58d1, when a rotating axis 52 is rotated, the contact 58d1 slides on the contact board 59k to change over the switch, a second extruded part 54d of the plate spring 54 for click is disengaged to the projected part 53b of the click member 53, and subsequently the first extruded part 54c of the plate spring 54 for click is disengaged to the engaged projected part 53a of the click member 53, thereby resulting in generation of different feelings of click.

Description

Technical field [0001] The present invention relates to a variable resistor with a switch that has a switch unit and a resistor unit, and has a key mechanism that generates a key touch feeling when a rotating shaft rotates. Background technique [0002] As a conventional technique of such a variable resistor with a switch, there is a technique described in Patent Document 1, for example. Figure 11-14 Is a diagram showing the variable resistor with switch described in Patent Document 1. Picture 11 Is a sectional view, Picture 12 Yes means Picture 11 The top view of the switch unit on the variable resistor with switch shown, Figure 13 Yes means Picture 11 The top view of the key board on the variable resistor with switch shown, Figure 14 Yes Picture 11 An explanatory diagram of the operation of the key mechanism included in the variable resistor with switch shown. [0003] Figure 11-14 The conventional technology shown has a shaft holder 1, a rotating shaft rotatably held...
