Abstract

PURPOSE:To expand the response range of the operating structure without increasing the occupied space by integrating both switches so that the rotating operation of the first switches and the depressing operation of the second switches do not interfere with each other. CONSTITUTION:A composite switch is constituted of a selector switch assembly 20 rotating the two first switches 31, 31 and a push button switch assembly 30 pressing the two second switches 32, 32. When the selector ring 11 of the selector switch assembly 20 is rotated, the cam face of a notch cam 14 depresses a notch ring 3 against a spring 12, a control cam 15 is rotated, and its cam face depresses push pieces 16, 16 to control the first switches 31, 31. When the push bar 21 of the push button switch assembly 30 is depressed, the two second switches 32, 32 are operated by the push plate 22 fixed at the tip of the push bar 21. The response range of the operating structure is thereby expanded, and the occupied space is shrunk.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a composite switch that integrates a selection switch for controlling a switching device and a push button switch for other operations.

[Conventional technology]

For example, the switches shown in FIGS. 4 and 5 are known as such rice switches. First, the one in Figure 4 is a push button switch with a selection ring.

Grooves 42 for controlling the push button switch 50 are formed on the outer periphery of the cylindrical push rod 41 at positions shifted by 180°.

The push rod 41 is also provided with a rotary cylinder 44 connected to the selection ring 43 and transmitting rotational force on the outside thereof, and the one-turn cylinder 44 has protrusions 45, 45 formed opposite to each other on the inner wall to engage with the groove 42 of the push rod 41. ing.

Note that the groove 42 allows the push rod 41 to be moved in the axial direction by the projections 45 and 45 when the rotary cylinder 44 that interlocks with the selection ring 43 rotates.

It is provided so that a push operation can be performed at a specified position. Further, an inner cam 46 is fitted into the push rod 41 to move the push piece 47 following the axial movement of the push rod 41, thereby driving the operating portion 50a of the push button switch 50.

Next, the one in FIG. 5 is a selection switch.

The notch cam 51 has a control cam 52 inside and a mouth transmission tube 53.
A knob 54 is fitted and connected to the one-rotation cylinder 53 inserted therein. When you turn the knob 54, the Notchicam 51
rotates and engages the cam surface of the notch cam 51, causing the spring 55 to rotate.
The vertical movement of the cam ring 56, which is biased by the cam ring 56, provides a notch sensation. Further, the control cam 52 rotates in conjunction with the notch cam 51 to move the push piece 57 and drive the operating portion 50a of the push button switch 50.

[Problem that the invention seeks to solve]

In such a conventional device, the push button switch with a selection ring shown in FIG. 4 has a structure in which the rotation of the first selection ring 43 and the movement of the push operation are linked, and the switches of the respective operation parts cannot be controlled. Further, the groove 42 formed on the outer periphery of the push rod 41 has the disadvantage that it is difficult to form a complicated shape and cannot correspond to various kinds of programs. Although the selection switch shown in FIG. 5 has the advantage of being able to support a variety of programs by changing the control cam 52, the push-operated switch can be had to be installed separately, which had the disadvantage of requiring a large amount of space.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks, and provide a composite switch that integrates a twist operation selector switch and a push operation switch, which can accommodate a wide variety of operation configurations without increasing the size. It's about doing.

[Means for solving problems]

This invention aims to achieve the foregoing objectives.

A selection ring that protrudes from the front side of the upper frame and is rotatably guided by a cylindrical part that also serves as a mounting structure for the top panel; a spring-loaded notch ring that is coupled to the back end of the selection ring; a notch cam that is rotatably guided in the cylindrical portion in a lockable manner; a first switch that is operated by twisting the selection ring via a push piece that engages a control cam coupled to the notch cam; It is equipped with a second switch that is operated via a push plate fixed to the tip by the operation of a spring-biased push rod that is axially guided by the ring and the lower frame. [Operation] By twisting operation. By integrating the first switch and the push-operated second switch so that their operations do not interfere with each other, the range of operation configurations can be expanded without increasing the occupied space.

〔Example〕

1 to 3 are views showing one embodiment of a composite switch according to the present invention, and FIG. 1 is a longitudinal sectional view.

2 is an exploded perspective view of essential parts, and FIG. 3 is a sectional view taken along line I--■ in FIG. 1. In the figure, the combination switch is composed of a selection switch assembly 20 for twisting two first switches 31, 31, and a push button switch assembly 30 for pushing and operating two second switches 32, 32. has been done. The selection switch assembly 20 is provided protruding from the front side of the upper frame I, and includes a selection ring 11 that is rotatably guided by axial restraint in a cylindrical portion 1a that is fastened to the panel 10 by a link nut 2, and a selection ring 11 that is rotatably guided by axial restraint. Groove 11 on the back side of ring 11
a notch cam 14 that can be fitted and coupled to a notch ring 13 that is biased by a spring 12 guided to the lower frame 3 and can move up and down; a control cam 15 that is fitted and coupled inside the notch cam 14; 15 and presses the operation parts 31a, 31a of the first switch 31.31 by twisting the selection ring 11.

The push rod 21 is rotatably guided by the selection ring 11 and the lower frame 3, and the second switches 32, 32 . . are fixed to the lower end surface of the push rod 21. Operation unit 32a.

32a, and a spring 23 which is elastically loaded between the stepped portion of the push rod 21 and the lower frame 3 and urges the push rod 21 upward.

In the above configuration, the selection switch assembly 20 and the pushbutton switch assembly 30 can be operated independently without interfering with each other, and the selection switch string 20 can be rotated by twisting the selection ring 11 to control the notch cam 14. At the same time as the cam surface pushes down the notch ring 13 against the spring 12,
The control cam 15 rotates and its cam surface presses down on the push pieces 16, 16 to actuate the first switch 31.31. Further, in the push button switch assembly 30, when the push rod 21 is pushed, the two second switches 32 and 32 are operated by the push plate 22 fixed to the tip of the push rod 21. Therefore, selection switch assembly 20 and pushbutton switch assembly 3
0, it becomes possible to associate a program with an expanded degree of freedom, making it possible to expand the range of motion configurations and reduce the occupied space.

〔Effect of the invention〕

According to this invention, by configuring the selection switch assembly and the pushbutton switch assembly that require other operations so that they do not interfere with each other, it is possible to handle complex control and expand the occupied space. It is possible to provide a composite switch that is not
