Description

[Detailed Description of the Invention] This invention relates to a rotary bush switch that displays operation and switches a plurality of contacts by pressing the switch.

Switches used in electrical circuits include rotary switches whose coaxial contacts turn ON and OFF by rotating a shaft, pushbutton switches which repeatedly turn ON and OFF by pressing, and switches that turn ON and OFF by rotating a lever. There are various types of switches, such as lever switches that turn OFF, but rotary switches have a knob attached to the tip of the shaft and are rotated, so they require a large space on the panel surface for the knob to rotate. Shuttle switches require less space on the panel surface, but they cannot have many contacts, and like rotary switches, lever switches require more space on the panel than bush switches. was there.

This idea was made to eliminate the above-mentioned drawbacks, and it is a new type of rotary bush switch that requires less space on the panel surface, yet can have many contacts like a rotary switch. The purpose is to provide

Embodiments of this invention will be described below with reference to FIGS. 1 to 13.

1 to 3 are schematic diagrams showing examples of the use of the rotary bush switch according to this invention. In the figures, reference numeral 1 denotes a switch operating body, which is attached to a panel 5.

2 is a movable body of the switch operating body 1.

As will be described later, the movable body 2 is configured to rotate around an axis and move in stages in the axial direction by pressing a bushing knob.

Reference numeral 3 denotes a slide switch connected to the movable body 2 via a connecting rod 4, which is switched by the movement of the movable body 2 in the axial direction.

In addition, FIG. 1 illustrates a case in which the movable body 2 and the connecting rod 4 are connected by a universal joint 4a, and the slide switch 3 is remotely operated.If this is not necessary, FIG. Alternatively, as shown in FIG. 3, the slide switch 3 may be directly connected to the movable body 2, and the connecting rod 4 may be omitted.

4 to 12 show the constituent members of the switch operating body 1, in which the movable body 2 includes a round bar portion 21. It consists of a square bar part 22 and a cylindrical part 23, and is housed in the cylindrical cover 6 so that the tip of the round bar part 21 protrudes from the cover 6.

Reference numeral 7 denotes a knob, and when pressed, the movable body 2 is operated via the push-out pin 8.

9 is a nut for fixing the cover 6 to the panel 5;
10 is a shaft support plate fitted to the rear end of the cover 6 to support the round bar portion 21; 11 is a coil spring for urging the movable body 2 to move in the knob 7 direction; , is inserted between the shaft support plate 10 and the cylindrical portion 23.

12 is a coil spring inserted between the locking part 61 formed on the inner wall of the cover 6 and the push-out pin 8,
The knob 7 is always kept in a normally protruding state via an ejector pin 8.

Around the cylindrical portion 23, trapezoidal stoppers 24 to 27 are provided protruding from the outer periphery at a 90° angle as shown.

On the inner wall of the cover 6, there is a first. Second and third guides 62, 63, and 64 are protruded, and the positional relationship and shape of these guides are as shown in FIG.

The first guide 62 extends forward from the rear end side (the above-mentioned shaft support plate 10 side) in a band shape by a predetermined length, and has an inclined side 62a formed at its tip.

The second guide 63 has a wider width (
The trailing edge has an inclined side 63.
a, and the longest edge is the first guide 6.
It ended around 2.

Further, the inner edge 63 b is in a positional relationship such that it is in a straight line with the outer edge 62 b of the first guide 62 .

The third guide 64 extends rearward from the locking portion 61 side,
It is parallel to the second guide 63 and has a band shape, and a guide groove 64a is formed between the guide groove 64a and the inner edge 63b, and the end thereof is located approximately in the middle of the inner edge 63b.

The knob 7 is a cylindrical body with a two-stage outer shape, with a small diameter on the back side and a large diameter on the front side, and a slide hole 71 with a square cross section is formed from the rear end, through which the square bar part 22 of the movable body 2 slides. It is now possible to do so.

Therefore, the movable body 2 can slide relative to the knob 7, but when the movable body 2 rotates, the knob 7 also rotates.

A claw 72 is formed at the rear end of the knob 7, and the locking portion 6
1 and is held so that it cannot be pulled out.

An indicator 73 is provided on the front surface 74 of the knob 7, and in the illustrated example, a groove is formed and this is used as an indicator.

As shown in FIG. 8, the push-out pin 8 has a non-gang portion that is slidably fitted into the small diameter portion of the knob 7, and a push-out guide piece 8.
1 and a stopper piece 82.82 for setting the slide stroke of the knob 7.
82 also serves as a spring receiver for the coil spring 12.

An inclined side is formed at the tip of the extrusion guide piece 81,
As a result, the stoppers 24 to 27 are successively pushed out rearward.

FIG. 13 is a developed view for explaining an example of the operation of the switch operating body 1 having the above-mentioned configuration. The inclined side 63a of the second guide 63 is the same inclined surface, while the stopper 24, the extrusion guide piece 81 and the first
Since each contact side of the guide 62 is inclined as shown in the figure, the stopper 24 is sandwiched between the inclined side at the tip of the extrusion guide piece 81 and the inclined side 62a at the tip of the first guide 62. The inclined side 63a of the guide 63 is pushed out in the direction a.

Since the movable body 2 is always urged forward by the coil spring 11, the stopper 24 slides on the inclined side 63a, and the movable body 2 rotates accordingly.

In this state, the stopper 25, which is 90 degrees misaligned with the stopper 24, has rotated toward the inner edge 63b of the second guide 63, and finally the stopper 25 is rotated toward the inner edge 63b of the second guide 63.
b, the rotation of the movable body 2 is stopped, and the stopper 24 becomes locked to the end of the inclined side 63H.

As a result, the movable body 2 is rotated by 90 degrees.

In addition, when slowly releasing the push-in of the knob 7, the next stopper 25 once hits the side edge of the extrusion guide piece 81 during the above operation explanation, but when the extrusion guide piece 81 is retracted, it touches the inner edge 63b. come into contact with

As described above, the movable body 2 moves one step backward (upward in the figure) while rotating around the 90' axis, and the slide switch 3
(See FIGS. 1 to 3) can be switched.

At this time, since the knob 7 also rotates, the operation display is performed by the direction of the indicator 73 in accordance with the rotation of the movable body 2 around the axis.

When the movable body 2 rotates around the axis in this way, the stopper 2
4 to 27 move as shown by the arrows in the figure, and then change their positions at 90'.

Therefore, if the knob 7 is pressed again, the stopper 25 will move in the same way as the stopper 24 described above, and the movable body 2 will move 90° again.
While rotating around the axis, the slide switch 3 can be moved upward by one step to switch the slide switch 3 and to display the operation display.

The stoppers 26 and 27 operate in the same manner.

In this embodiment, the four stoppers 24 to 27 are arranged with angular differences of 90 degrees, so the switching operation is performed in four stages. By arranging them at intervals, the number of switching operation steps can be increased or decreased.

According to the rotary bushing switch of the present invention, since the slide switch is coupled to a movable body that moves step by step in the axial direction when the knob is pressed, the operation is similar to that of a bushing switch. You can switch a long-stroke, multi-stage slide switch with just a single button, and since only a button-type knob protrudes from the panel surface, less space is required for operation, and it is generally suitable for electronic devices with a small panel surface. It is ideal when using a multi-contact switch that performs multi-stage switching.

Furthermore, since the knob rotates as the slide switch is switched, the switching position of the slide switch can be displayed accurately and easily as a display means by rotating the display.
