Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in the rosette structure of an operating switch having a rosette portion.

An operation switch that has a rosette part, such as a selector switch (a switch that is selectively opened and closed by key operation, and has a structure in which the main body of the switch is inserted from the front side of the panel and then fixed by tightening a nut from the back side of the panel) has a rosette part on its mounting surface. Various rosette shapes are commercially available. Figure 1 shows an example of typical surface shapes; a rectangle in Figure 1a, a square in Figure 1B, and a square in Figure 1B.
A design shape suitable for the panel to be attached is selected, such as the circular shape shown in Figure c. In this way, even if we simply take only the surface shape, there are many types (there are also differences depending on color, material, etc.), and there is a risk that a large number of different types will be produced in small quantities. A vertical cross-section of the conventional structure of this type of selector switch is shown in Figure 2.
FIG. 3 shows a longitudinal section taken along the line - in FIG. 2 in the direction of the arrows. In the figure, reference numeral 1 denotes a rosette portion having various surface shapes, and is structured to be attached by tightening a nut 3 with a panel 2 to be attached sandwiched therebetween. To roughly explain the structure and operation of the main body part, first, by twisting the inserted key 4, the rotor 5 and the piece 6 linked thereto rotate, and the leg 7 of the piece 6 moves against the cam surface of the push rod 8. By sliding on the push rod 9, the push rod 8 is pushed down against the back spring 11 while being guided by the guide 10.
With this movement, the push piece 13 that drives the contact portion 12 is pressed, and the contact portion 12 is operated. Due to this operation, the contact portion 1 is changed depending on the rotational position of the key 4.
2. Select open or closed state. When replacing a selector switch with this type of structure due to a change in the surface shape of the rosette, it is not possible to replace only the rosette part; the entire switch must be kept in stock according to the surface shape of the rosette, which is extremely difficult in terms of inventory management. It was inconvenient.

The object of this invention is to eliminate the above-mentioned drawbacks and provide a selector switch that facilitates inventory control.

According to this invention, this can be achieved by dividing the rosette into two parts, separating it into a flange part and a body part, and by constructing the flange part so that it can be easily replaced at any time.

Embodiments of this invention will be described in detail below based on the drawings. FIG. 4 is a longitudinal sectional view of a selector switch according to an embodiment of the invention, and FIG. 5 is a longitudinal sectional view taken along the line - in FIG.
Based on the present invention, the rosette portion in the conventional structure is divided into a flange portion 1a and a sleeve-like body portion 1b that fits into the flange portion 1a. This flange part 1
A and the body portion 1b are attached by tightening nuts 3 with the panel 2 sandwiched between them, as shown in FIGS. 4 and 5. By tightening the nut 3, the stepped portion 14 of the flange portion 1a and the jaw portion 15 of the body portion 1b are brought into close alignment. The combination of the flange portion 1a and the body portion 1b will be explained in detail with reference to FIGS. 6 and 7. FIG. 6 is a cross-sectional view taken along the - line in FIG. 4, and FIG. Part 1a
It is a perspective view of the flange portion 1a, and a rib 16 is provided on the flange portion 1a.
is provided, and is positioned in the rotational direction by fitting into a groove 17 provided in the body portion 1b, that is, by spline connection. Flange part 1
As an example, a has a shape as shown in FIG. 7 a, b, and c, but it can also be easily combined with any other shape. FIG. 8 is a perspective view of the main body of the selector switch to which the flange portion 1a is not yet attached, and when the flange portion 1a of any shape is combined with this, the contact portion 12 is
Insert the flange portion 1a from the side. Thereafter, the rib 16 on the flange portion 1a is aligned with the groove 17 on the body portion 1b, and the stepped portion 14 is brought into contact with the jaw portion 15 to be assembled.

As described above, the present invention is constructed by dividing the rosette part for attaching the operating switch to the panel into a flange part that comes into contact with the panel surface and a sleeve-shaped body part that passes through the mounting hole of the panel. The body part is spline-coupled to the body part, and a step part is provided at the entrance of the body part insertion hole of the flange part to receive the jaw part protruding from the outer periphery of the end part of the body part, so that the shape of the flange part is different. By preparing different types of items separately,
By preparing only one standard type of switch body, it is possible to obtain a wide variety of operation switches that can meet many requirements, which has the effect of facilitating production control. Even if the rosette part is divided into a flange part and a body part, both are spline-coupled, and the jaws protruding from the outer periphery of the stepped body part provided near the entrance of the opening of the flange part are received. Therefore, when it is attached to a panel, the body part is tightened with a nut inside the panel, and the flange part is pressed against the panel surface and fixed, so it is completely different from the conventional operating switch with an integrated rosette. Similarly, it also has the effect of being able to be reliably attached to a panel.

This invention can be applied not only to the above-mentioned selector switch but also to other general operation switches having a rosette portion.
