The above has described the knob 15 on the right side housed in the mounting hole 13 of the auxiliary machine frame 3, the related working claw 22, and the parts and structures related thereto. The knob 15' on the left side, which is housed in the mounting hole 13' of the auxiliary frame part 3 in such a manner, also has an operating pawl 22' and related parts similar to those described above.
Structures are provided and implemented, and identical parts are indicated by a dash (') appended to their reference numerals.

Next, the operation of this embodiment will be explained. Now, as shown in FIG. 1, if one of the knobs 15, 15' held at the original position above, for example, knob 15, is pressed downward in a direction perpendicular to the moving direction of the holder 7, the support shaft Since the working pawl 22 is also pressed downward through the knob 23, the working pawl 22 also descends together with the knob 15 as shown in FIG.
comes to engage with the engaging claw 11. Further, when the knob 15 is pressed, the working claw 22 is moved with the claw portion 25 engaged with the engaging claw 11 as shown in FIG.
begins to rotate in the direction opposite to the direction of arrow 27, and as a result, the claw portion 25 presses the engaging claw 11 to the left, so that the holder 7 is moved to the left. Then, the holder 7 is inserted by one claw of the engaging claw 11 (1
When the holder 7 is moved to the left by an amount corresponding to the pitch, the stopper protrusion 18 engages with the engagement claw 12 to prevent further leftward movement of the holder 7, as shown in FIG. , this means that the holder 7 has been moved one pitch in the left direction. After that, when the pressing operation force on the knob 15 is released, the knob 1
5 is raised by the spring force of the compression coil spring 20, and the working pawl 22 is rotated in the direction of arrow 27 by the spring force of the torsion coil spring 26, returning to the original position shown in FIG.
Thereafter, by repeating the pressing operation and release of the knob 15 in the same manner, the working claw 22 sequentially engages and disengages from the plurality of engaging claws 11, and the holder 7 is sequentially moved leftward. Then, as the holder 7 moves leftward, the movable contacts 10 of the contact plate 9 come into selective contact with the plurality of fixed contacts 6 of the board 5, and thus the switch switching operation is performed. will be carried out.

In addition, when the knob 15' is pressed, the working pawl 22' comes to engage with the engaging pawl 12, and in this case, the engaging pawl 12 forms an inclination opposite to that of the engaging pawl 11. Since the working claw 22' is left-right symmetrical with respect to the working claw 22, the holder 7 is moved rightward.

As described above, according to this embodiment, the holder 7 is moved forward by repeating the pressing operation and release of the knob 15 or 15', so that small-scale operations can be performed.
Unlike conventional sliding switch devices, there is no possibility of overrun due to excessive operating force. 2
2' is made to engage and disengage from the engaging claw 11 or 12 of the holder 7 which is slidably provided on the machine frame 2 of the device body 1, so that only the holder 7 is advanced and the knob 15 is moved together with the holder 7. and 15' are also not stepped, thus improving operability. Moreover, for example, the support shaft 23 of the working claw 22 is rotatably supported by the support grooves 17a, 17a of the knob 15 and movable in the left-right direction, and the pivot shaft 24 of the working claw 22 is supported by the partition wall in the container body 1. 14
Since the rotatable and vertically movable pivots are provided in the support grooves 21a, 21a of the knob 15, when the claw portion 25 of the working claw 22 engages with the engagement claw 11, no pressing operation force is applied to the knob 15. Working claw 22 as it is
This is transmitted as a rotational force to the holder 7, and is immediately transmitted as a force to move the holder 7 to the left.
Since the pushing force on the knob 15 is converted into stepping force on the holder 7 with high efficiency, the pushing force on the knob 15 can be small, resulting in excellent operability.

Although the above embodiment describes the case where the present invention is applied to a sliding switch device, it may also be applied to a variable resistor by, for example, installing a substrate provided with a resistance band in place of the substrate 5. Alternatively, the present invention can be applied to any device requiring a stepping device, such as a heater control device by connecting the holder 7 to a damper of a heater control via a flexible wire.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can of course be implemented with appropriate modifications within the scope of the gist.

[Effect of idea]

As explained above, the stepping device of the present invention has a knob on the body and a holder having an engaging claw, and each time the knob is pressed, the stepping device sequentially engages the engaging claw to move the holder. A roughly dogleg-shaped working claw for advancing the knob is rotatably mounted on the knob, and is rotatably mounted on the container body so as to be movable in the direction of movement of the knob, so that the knob can be pressed to operate. The holder can be moved forward by one pitch with just a simple operation, and the holder only moves forward without the knob moving together with the holder. can be converted into stepping force with high efficiency,
This provides effects such as improved operability.
