Abstract

A variable resistor with a switch, the key mechanism has a key member (53) and a plate spring (54) for the key, the resistor unit has a resistance substrate (57k) and a first slide key including a contact point (58a1), and a rotary switch There is a second insulating case (59) as a contact substrate and a second slide key including a contact (58d1), and when the rotating shaft (52) is rotated, the contact (58d1) slides on the contact substrate part (59k) to perform When the switch is switched, the second bulging part (54d) of the leaf spring (54) for the key is engaged with the protrusion (53b) of the key member (53) and disengaged, and then the first bulge of the leaf spring (54) for the key is released. The part (54c) engages and disengages from the engaging protrusion (53a) of the key component (53), thereby producing different key tactile sensations. Such a variable resistor with a switch can obtain a key touch feeling that does not produce an uncomfortable feeling and can reduce the shape of the switch part.

Description

technical field [0001] The present invention relates to a variable resistor with a switch, which has a switch unit and a resistor unit, and has a key mechanism that produces a key tactile sensation when a rotating shaft is rotated. Background technique [0002] As a conventional technology of such a variable resistor with a switch, there is a technology described in Patent Document 1, for example. Figure 11-14 It is a figure showing the variable resistor with a switch described in this patent document 1, Figure 11 is a sectional view, Figure 12 yes means Figure 11 Top view of the switching unit on the shown variable resistor with switch, Figure 13 yes means Figure 11 Top view of the keypad on the rheostat with switch shown, Figure 14 yes Figure 11 An explanatory diagram of the operation of the key mechanism provided on the variable resistor with switch shown. [0003] Figure 11-14 The conventional technology shown has a shaft base 1, a rotating shaft rotatably...
