It is an object of the present invention to provide a switch operation mechanism capable of reducing manufacturing costs.

Summary of the invention In order to achieve the above object, the present invention provides a switch operation comprising a switch, a connector connected to one end of the switch, and a knob connected to the other end of the connector. In the mechanism, the connector includes a trunk and a pair of branches that are formed into a substantially V-shaped bifurcated shape in at least one of the horizontal and vertical directions and are connected to one end of the trunk. are formed into a substantially Y-shape by integrally molding the two branches, and the distal ends of the pair of branch parts are provided with an inclined part in at least one of the branch parts, so that the distal ends of the pair of branch parts can be formed in a horizontal direction or in a longitudinal direction. The switches are also offset from each other in the other direction.
A pair of knob joints are connected to the switch joint provided at the other end of the trunk, and a pair of knob joints are provided at the tips of the pair of branch parts, and one of the pair of knob joints is connected to the switch joint provided at the other end of the trunk. and the other end is left as a free end without being associated with the knob, so that the connector can be commonly used for connecting the knob and the switch for a plurality of devices in which the relative positions of the knob and the switch are different. It was configured as follows.

With the above configuration, even if the relative positions of the knob and the switch are different, a single connector can be used in multiple ways, and mold manufacturing costs can be reduced.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 2 to 4B.

The switch operation mechanism basically consists of a push switch 2, a connector 11, and a knob 4a or 4b.

The connector 11 has a generally Y-shaped structure as a whole, and is made of members each having a U-shaped cross section. That is, the connector 11 is formed into a bifurcated shape that is approximately V-shaped in the lateral direction, and is connected to the trunk 11a.
A pair of branches 11b, 1 connected to one end of 1a
1c and are integrally molded from synthetic resin such as ABS resin or PS (polystyrene). A rectangular recess 13 and a slit 14 into which the switch shaft 12 of the push switch 2 is fitted from the direction of arrow a are formed at one end of the trunk 11a.

Fitting shafts 15a and 15b having a predetermined length and a rectangular cross section are formed at the distal ends of the pair of branch parts 11b and 11c, respectively. Further, the branch portion 11b is provided with an inclined portion 28. A fitting shaft 15 is formed at the tip of the pair of branch parts 11b and 11c.
As clearly shown in FIG. 4B, a and 15b are also vertically displaced from each other due to the above-mentioned inclined portion. Therefore, these fitting shafts 15a, 1
5b, as shown in FIGS. 4A and 4B, are located at different predetermined relative positions with respect to the switch 2 in the horizontal and vertical directions. For example, the fitting shaft 15a corresponds to the set A, and the fitting shaft 15a corresponds to the set B. The fitting shaft 15b is configured to correspond to the fitting shaft 15b.

Therefore, when this connector 11 is used, for example, in set A, the recess 1 at one end of this connector 11 is
3 and the slit 14 from the direction of the arrow a to connect it to the switch 2, and connect the knob 4a to the fitting shaft 15a. Also, set this connector 11 to
When used as
It is sufficient if the knob 4b is connected to the knob 4b. Therefore, this connector 11 can be used in two ways, and can be used in common with two sets in which the relative positions of the knob and the switch are different. Also, in this case, connector 1
The switch shaft has a concave portion 13, a slit 14, a connecting portion between the fitting shafts 15a and 15b, and the knob so that it can be connected to the switch and the knob even if the switch 1 is turned upside down. Therefore, if the connector 11 is turned upside down, it can be used in two additional ways.

Note that the knob 4b to which the fitting shaft 15b is attached
(The same applies to the knob 4a to which the fitting shaft 15a is attached) is provided with an intermediate member 16. The fitting shaft 15b is connected to this intermediate member 16.
It is elastically attached to the knob 4b via.

That is, the intermediate member 16 integrally molded from synthetic resin or the like includes an outer square tube part 17 and an inner square tube part 1.
8. And these square tube parts 1
7 and 18 are formed integrally with each other by elastic pieces 19 facing each other. In addition, the inner square tube part 1
8 is arranged approximately in the center of the intermediate member 16 by an elastic piece 19, and the connector 1 is attached to this inner square tube part 18.
The first fitting shaft 15b is fitted from the direction of arrow b.
Since the elastic piece 19 is formed to have a thin wall and a narrow width so as to be rich in elasticity, the fitting shaft 15b of the fitted connector 11 can be attached to the inner square tube part in all directions except the pressing operation direction. With 18,
It is elastically movable relative to the outer corner tube portion 17.

On the other hand, a knob 4 integrally molded from synthetic resin etc.
A rectangular tube portion 20 is formed in b. and,
A protrusion 23 having an inclined surface 22 of the outer square tube portion 17 of the intermediate member 16 is engaged with the opening 21 provided on two opposing sides of the square tube portion 20 from the direction of arrow c. As a result, the knob 4b and the outer rectangular tube portion 17 are tightly coupled without wobbling, and in this state, the knob 4b is attached to the panel 3b via the escutcheon 24. However, the fitting shaft 15b of the outer square tube portion 17 and the connector 11
As mentioned above, since the elastic piece 19 is interposed between the knob 4b and the switch 2, the elastic piece 19 With this intervention, the switch 2 can be operated from the knob 4b via the connector 11. That is, by pressing the knob 4b, for example, the switch shaft 12 moves against the compression spring 25, and as a result of this movement, the connector provided on the switch shaft 12 comes into contact with the desired connection terminal 26. The desired switching action takes place.

Effects of the invention As explained above, in the switch operation mechanism according to the invention, two
Although the connector is a component and can be used in multiple ways, the connector is almost Y-shaped and allows the tip of one of the pair of branches to be selectively connected to the knob. It is excellent in terms of strength and space factor. In particular, since the pair of branches of the connector are shifted in both the horizontal and vertical directions, if the connector is used upside down, it can be used in four ways. Therefore, according to the present invention, the manufacturing cost of the connector mold is greatly reduced, which improves the effectiveness of mass production, which is very advantageous.
