Description

[Detailed Description of the Invention] This invention relates to a switch in which a pointer indicates the on/off state based on the operation of an operating handle that is opened and closed by pulling the operating string.

For switches whose height dimension is smaller than their horizontal dimension, it is conceivable to stack a plurality of switches in the height direction in order to effectively utilize the installation space. However, since the operating handle for opening and closing the switch is operated by pulling the operating string, simply stacking the switches in the height direction may interfere with the operation of the pulling string. Become.

Therefore, in order to avoid hindrance to the pull cord operation, it is conceivable to use the entire switch stacked vertically as described above horizontally, but in this case, the pull cord cannot be used as is. This may cause problems with opening/closing operations, or make it difficult to distinguish between on/off indications.

This invention was made in order to improve the above-mentioned problems, and includes an operating shaft and a pointer shaft that protrude from the switch case, and an operating handle and a pointer shaft that are respectively attached and fixed to these shafts. A mounting means is provided between the pointer and the pointer so that the mounting position of the operation handle and the pointer can be changed when rotated 90 degrees around each axis, and the pointer operates based on the operation of the handle to indicate the on/off state. A fixing means is provided between the display board for display and the case to change the fixing position of the display board to a position rotated 90 degrees around the pointer shaft in the same direction as the direction in which the pointer mounting position is changed. Accordingly, it is an object of the present invention to provide a switch which can be installed either vertically or horizontally, and which makes effective use of the installation space.

Hereinafter, the first embodiment of this invention will be described with reference to FIGS. 1 to 4. On the upper surface of the switch case 2, from which bushings 1 for each phase are protruded from both sides, a pair of front and rear mounting plates are provided. 3 are welded to each other, and a spacer plate 4 is bolted to each mounting plate 3.
A pair of J-bolts 5 is inserted through each spacer plate 4, and a cross-piece 7 is inserted between the pair of J-bolts 5 and the upper surface of the spacer plate 4 by a nut 6 screwed thereto. A fixing plate 8 for clamping is fitted.

The fixing position of the display board 23 is fixed around the pointer shaft (operating shaft 11) using the book mounting bolt 13 and the mounting hole 24.
Fixing means are configured for changing to a 90 degree rotated position.

Now, when the switch configured as described above is placed horizontally as shown in FIG. In use, the handle 15 is attached and the display plate 23 is attached to the two mounting bolts 13 on the bottom side of the case 2 as shown in FIG. At this time, by operating the pull string on the operating handle 15, the pointer 20 externally displays the on/off state as shown by solid lines and chain lines in FIG.

Next, as shown in Fig. 4, attach the switch to the mounting frame 2.

Next, a second embodiment of the mounting means is shown in FIGS. 5 and 6.
To explain according to the diagram, in this embodiment, the operation axis 1
A notch groove 31 larger than 90 degrees is formed on the circumferential side of the 0, and an engaging protrusion 32 is provided on the inner periphery of the operating handle 15 and the boss 14 to be rotatably engaged with the notch groove 31 by 90 degrees. The mounting position of the handle 15 relative to the handle 10 is changed by using a key 33 which forms a quarter-arc shape and engages with a notched groove. In this case, the mounting position can be easily changed by removing the key 33.

Further, another example of the mounting means will be explained with reference to FIGS. 7 and 8. First, in FIG. Stop hole 34 and boss 14
An engagement hole 35 is transparently provided so as to pass through its axis.

As mentioned above, in this invention, there is a distance between the operating shaft and pointer shaft protruding from the switch case and the operating handle and pointer that are respectively attached and fixed to these shafts. A mounting means is provided to change the mounting position of the operation handle and the pointer when rotated, and a pointer is mounted between the case and the display plate for indicating the on/off state using the pointer, centered around the pointer shaft. By applying a fixing means to change the fixed position of the display board to a position rotated 90 degrees in the same direction as the direction of change of position, the installation state of the switch can be changed to either vertical or horizontal installation. This is a practically preferable idea for a switch because it has the effect of making it possible to effectively utilize the installation space.

Note that 90 degrees in this invention does not necessarily mean exactly 90 degrees.
It is not limited to the pointer axis, but includes cases where it is slightly shifted before or after it, and the center when changing the mounting position of the mounting plate is not necessarily limited to the point that coincides with the pointer axis, but in the vicinity It also includes. Furthermore, the display board is not limited to one that indicates the on/off state, but substantially includes one that indicates power switching between the regular side and the standby side. Furthermore, this invention is not limited to the above-mentioned examples, and can be modified as desired without departing from the spirit of this invention.

Although not directly related to this invention, for example, in the first embodiment, the cross section of the fitting portion 11 is made a regular hexagon, and the mounting bolts 13 are arranged at each point forming a diagonal triangle with an apex angle of 120 degrees. If it is installed at a 60-degree angle, the switch can be installed at an angle of 60 degrees.
