2. Description of the Related Art Control devices and display devices of construction machines and the like are:
In general, besides the function of performing a normal operation, an additional function is provided, for example, for enabling calibration of the movement of an arm with respect to a lever of a construction machine. In addition to the group of switches for performing the normal operation, a switch for a specific purpose (referred to as a service switch) that must not be used in the normal operation, such as a changeover switch for changing the control device to the additional function state, is provided. That is, in addition to performing the calibration, the service switch stores control parameters for correcting variations in input characteristics of components constituting the control system, and stores input / output data from each component constituting the control system. It is used for displaying an input / output monitor self-diagnosis record for checking the actual state of the machine.

Incidentally, if the operator accidentally turns on the service switch during normal work, which is the original purpose, the operation state of the control device is changed, and not only work cannot be performed, but also danger may be involved. Therefore, normal control devices and display devices should be installed in such a position that the service switch cannot be operated by the operator in a normal position, or provided with metal fittings that fix the switch so that it does not work even if the service switch is accidentally touched. Had been taken. Therefore, when performing a calibration operation of a control device or the like to which a conventional service switch is attached, there have been problems that an excessive posture is imposed on a worker, work is difficult, and work efficiency is poor.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the drawbacks of the above-mentioned conventional apparatus, and a switch for normal work and a service switch for additional functions such as calibration work are the same. The service switch is mounted on the switch panel, and the service switch is hidden and installed so that the operator who performs normal operations does not notice or does not notice its existence, and the operation of the service switch is locked like a normal switch It is an object of the present invention to provide a switch panel that can be easily operated without requiring a special operation such as removing the switch panel.

[0005]

A for solving means] of the present invention for achieving the objects of the switch panel is configured as follows
ing.

That is, the switch panel of the present invention is:
Multiple switches that are turned on and off by a push member with return means
A switch panel comprising: a panel surface of the panel.
With a flexible sheet material and a plurality of switches.
Among them, at least the service switch for additional functions
Formed so that the tip of the push member does not protrude from the panel surface
And the sheet material is at least a normal work switch.
At least the back surface of the part facing the pressing member is formed in a convex shape
And the sheet contact part of the normal work switch
It is formed in a concave shape with respect to the convex surface.

[0007]

[Operation] A normal operation switch and an additional function service switch are arranged on the same switch panel, and the normal operation switch is projected from the panel surface to visually and tactilely confirm the position. Service switches are placed under the sheet material covering the panel surface, making it difficult to confirm the position not only visually but also tactilely. The configuration of the present invention makes the layout of each switch appropriate This prevents the operator performing normal work from accidentally touching the service switch. The flexible sheet material is not particularly limited, and for example, a rubber sheet or a flexible thermoplastic synthetic resin sheet can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. Switch panel 1 of embodiment 1 shown in FIG.
A switch 6 for normal operation formed by an electrode 2 formed of an elastic material such as a metal leaf spring and a fixed electrode 4 and a service switch 8 for an additional function having a similar structure are provided on a printed board 10 by a predetermined method. A switch group was formed by mounting the switches. Then , rod-shaped push members 12 and 14 for pressing the electrode 2 against the fixed electrode 4 were attached to the switches 6 and 8, respectively. As shown in the figure , the pressing members 12 and 14 are kept in a posture by a guide 16 and the surface thereof is
8 to form a membrane switch. In addition, the service switch 8, the official general worker also did not know of its existence is in, possible to adjust the trouble shoot to start the service function using the service man only is the switch 8 for maintenance Can be done.
Therefore, it is mounted at a position where the operator does not accidentally touch the service switch during normal operation.

[0009] Then, the distal end of the pusher member 12 normally attached to work switch 6 is mounted to protrude from the panel surface (the surface of the guide 16) 20, whereas the tip of the push member 12 attached to the service switch 8, Panel surface 2
0 to attached so as not to protrude. Also, sheet material 1
A portion where the tip 8 of the pressing member 12 is in contact with the cap member 22 which protrudes the sheet material 18 outward by embossing
Is formed, and the position of the switch 6 can be confirmed from the outside by covering the tip of the pressing member 12.

The switch panel 1 formed as described above
Your Pereta was placed in easy location and operation. Therefore, not only the operator who normally works, but also the service person who performs the work such as the calibration work and the service work becomes easy, and the work efficiency can be improved. Moreover, Operator normal operation, or not care-the presence of a service switch 8, it is possible to work without considering the service switch 8, additional function the device by touching the service switch 8 incorrectly in normal working It was possible to prevent the malfunction of switching to the mode.

If the location of the normal operation switch is colored by making it protrude by embossing as described above, the operator of the normal operation can more easily draw attention to the normal operation switch 6. Switch panel 1 of Example 2 shown in FIG. 2 is a front end of the pushing member 12 attached to the normal working switch 6 also mounted so as not to protrude from the panel face 20. Then, a push button 24 is formed to protrude from a portion of the sheet material 18 covering the panel surface 20 at a position corresponding to a portion where the push member 12 is arranged,
By pressing the push button 24 with a finger, the push member 1 is pressed.
2 was formed to be able to be pushed down.

As shown in FIG. 2, the push button 24 has a projection formed on the front surface and a projection formed on the back surface of the push button 24.
It is designed to cut into the inside to prevent the occurrence of displacement. Other parts are formed in the same manner as in the first embodiment shown in FIG. 1, and the same members as those in FIG. Note that the push button 24 may be solid or hollow. Further, a member corresponding to the button 24 may be formed as a separate member into a button shape and attached by a fixing means such as an adhesive.

[0013] switch panel 1 of Example 2 was formed as described above, in the same manner as in Example 1, it can also easily be confirmed even touch Satoshiteki normal visual position of the working switch 6 but operator normal operation, or not be aware of the service switch 8 can and this <br/> performing work without considering the malfunction can be prevented. The above push button is medium
It may be real or hollow. The means for thickening is the sheet material
