[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching state display structure for a switch.

[0002]

2. Description of the Related Art In general, a switch is provided with an opening / closing portion including a fixed electrode and a movable electrode which is in contact with and separated from the fixed electrode in a main body case thereof, and is used for operating a switching handle provided outside the case. Operating the mechanism for driving the opening / closing unit to determine whether the operating state is a closed state (“on”) or an open state (“off”) in the case of a manual type.
In the case of the automatic type, whether the state is the automatic state (“automatic”) or the manual state (“manually on”) is determined by associating the display pointer provided on the switching handle with the display written on the case. External display.

[0003]

However, with the recent trend toward downsizing switches, miniaturization of the main body case has been promoted, and switching of switches on the downsized case surface has been promoted in view of urban beautification. The space available for the status display is also limited to a small size.

It is an object of the present invention to provide a switch switching state display structure capable of suppressing the display space as small as possible and enabling the display state thereof to be easily visually checked.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides an "in", which is protruded from a switch case.
The switching operation handle for switching between “off”, “manually on”, and “automatic” is formed in a V-shape, and the bent portion is fixed to an operation shaft penetrating the switch body. The above-mentioned “enter”, on a substantially straight line sandwiching the operation shaft,
"Off" or "Manually on", "Automatic" display section is provided,
The switching operation handle is provided with a pair of display indicators projecting in the opposite bending direction to indicate each operation state, and the switch case is provided with a display indicator indicating a non-display portion different from the display indicator indicating the operation state. The gist of the present invention is that a shielding plate for covering is provided.

[0006]

According to the present invention constructed as described above, when the switch is operated by the switching handle, one of the display hands surely indicates the state in the vicinity of the operation axis in response to the operation with a small space. The other display pointer indicating the opposite display state at the time of display is hidden by a shielding plate provided on the switch case. Therefore, the display unit always has a small space of the switch case as a display unit that indicates only the corresponding state of the switch, so that the viewer can easily confirm the open / close state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. As shown in FIGS. 1 and 2, bushings 3, 4 on the load side and the power supply side are hermetically inserted into and attached to both side walls of the switch case 2 of the switch 1. The switch case 2 includes a switch (not shown) including a fixed electrode, a movable electrode, and the like, and a mechanism (not shown) for driving the switch to open and close.

Further, a handle shaft 5 as an operation shaft connected to the mechanism is protruded from the front surface of the switch case 2, and a switching handle 6 having a rectangular shape is provided at an end of the handle shaft 5. Are rotatably fixed. On a substantially straight line sandwiching the handle shaft 5 on the front surface of the switch case 2, a display 7 a indicating the closed state of the switch 1 is displayed by the letters “ON” on the left side with respect to the handle shaft 5. ing. On the right side, a display 7b indicating the open state of the switch 1 is displayed with the character "OFF".
Then, the indications 7a and 7b and the indicators 8a and 8
b, A display part is formed by a shielding plate, and is arranged at the lowermost end of the switch.

As shown in FIG. 3 and FIG.
A pair of hands 8a and 8b are attached to the outer edge of the intermediate bent portion. A substantially rectangular cover plate 9a, 9b for covering the pair of the display 7a or the display 7b is attached to the upper end of the switching handle 6 near the middle bent portion. Further, a mounting member 10 for mounting the switch 1 to a mounting bracket T fixed to the utility pole P is provided at the upper and lower ends of the switch case 2.
a, 10b are attached to the lower mounting member 10b.
Are provided with a pair of stoppers 11a and 11b for preventing the switching handle 6 from rotating.

Note that the lower mounting member 10b is provided with
When a and 8b are in the non-display state, they are also used as a shielding plate so as to cover the entire surface. Next, the operation of the switch 1 thus configured in the switching state display structure will be described.

When the switch 1 is manually turned on, the switching handle 6 is rotated clockwise about the handle shaft 5. Then, the switch 1 is turned on, and the rotation of the switching handle 6 is prevented by the stopper 11b. At this time,
The pointer 8a of the switching handle 6 points to the display 7a (“ON”) in the left direction (in FIG. 3). Also, the other pointer 8b
Is covered with a mounting member 10b, and a pointer 8 is used as a display pointer.
The viewer can recognize only the existence of a. Further, the cover plate 9b of the switching handle 6 covers a display 7b ("OFF") indicating the open state.

When the switch 1 is manually opened, the switching handle 6 is rotated counterclockwise about the handle shaft 5 from the closed state. Then, the switch 1 is opened and the switching handle 6 is prevented from rotating by the stopper 11a. At this time, at this time, the pointer 8b of the switching handle 6 is displayed in the rightward direction (in FIG. 4) 7b.
("OFF"). Further, the other hand 8a is covered with the mounting member 10b, and the viewer can recognize only the presence of the hand 8b as the display hand. Further, the cover plate 9a of the switching handle 6 covers a display 7a ("ON") indicating the closed state.

As described above, in the switching state display structure of the switch according to the present embodiment, one of the display hands surely indicates the state in the vicinity of the operation axis and displays the opposite display state in response to the operation. Is hidden by the mounting member 10b which also serves as a shielding plate provided in the switch case, so that the display space for the displays 7a and 7b can be reduced, and the displays 7a and 7b can be reduced.
7b is always present as a display unit indicating only the relevant display of the switch, so that the viewer can easily confirm the open / closed state.

In the switching handle 6 of this embodiment, cover plates 9a and 9b are provided on the switching handle 6 so as to cover the display 7a or the display 7b which indicates the state opposite to the closed state or the opened state. Thus, the open / closed state can be easily confirmed.

It should be noted that the present invention is not limited to the above embodiment, but may be made as follows without departing from the spirit of the present invention. (1) In the above embodiment, a manual switch is used. However, the present invention may be applied to an automatic switch. (2) In the above embodiment, the cover plates 9a and 9b are separately provided on the switching handle 6, but instead, each cover plate may be provided in an integral shape such as a fan shape.

[0016]

As described in detail above, according to the switch switching state display structure of the present invention, not only can the display space be reduced, but also the state of the switch can be easily confirmed. It works.
