Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waveform switch having a cover for preventing erroneous operation.

[0002]

[Prior Art]

 Conventional waveform switches have a strong need for simple and inexpensive general-purpose parts for indoor electrical and electronic equipment, so no special measures have been taken to prevent erroneous operation. In addition, even when measures are taken to prevent erroneous operation, it is common to implement the entire system including the waveform switch.

[0003]

[Problems to be solved by the device]

 However, although it is necessary to take some measures to prevent erroneous operation, it is time-consuming and time-consuming to implement the entire system as described above, and since it is not to prevent erroneous operation of the waveform switch itself, the waveform switch is inexpensive and versatile. There is a problem that the rich quality is lost.

The present invention has been made in view of the above problems, and an object thereof is to provide a waveform switch with an erroneous operation prevention cover having an erroneous operation prevention mechanism that is simple in structure and can be manufactured at low cost.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the corrugated switch with an erroneous operation prevention cover of the present invention is formed with a switch front plate having a guide groove at the side end and a U-shaped cross section with a downward opening, and the inner side of the lower end A cover provided with a protruding guide piece, and the guide piece is engaged with the guide groove to allow the cover to slide along the switch face plate and to contact the operating portion on the switch face plate. Instead, it is designed to cover half of this operating part.

[0006]

[Action]

 According to the erroneous operation prevention cover-equipped waveform switch configured as described above, by sliding the cover, it is possible to cover half of the protruding operation section, and protect the operation section from inadvertent pressing.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 is a waveform switch according to the present invention, which is composed of a switch front plate 2, a cover 3, an operating portion 5, and a switch body 6. Guide grooves 3 and 3 are provided in the longitudinal direction of both ends 2a and 2a of the switch face plate 2.

The cover 3 is formed by forming a flat plate into a U-shaped cross section with the opening facing downward, and guide pieces 4a, 4a protruding inward are provided at the lower ends of both side surfaces 4b, 4b, respectively. The upper surface is provided with a plurality of slits 4c. This cover 4 is attached to the switch front plate 2 as shown in FIG. 2 by expanding both side surfaces 4b, 4b and engaging the guide piece 4a with the guide groove 3, and along this guide groove 3 Slide in the longitudinal direction. The width of the cover 4 is large enough to cover one of the on-side and the off-side, which is half of the operating part 5, and the height of the cover 4 is slightly higher than the highest point of the operating part 5 protruding. Is becoming

Therefore, even with the cover 4 attached, the advantage of volume as a small switch is not lost. Further, by sliding the cover 4 in the longitudinal direction, it is possible to cover half of the operating section 5 without touching the protruding operating section 5 in the ON state or the OFF state, and carelessly touch the operating section 5 with a finger or the like. It is possible to prevent erroneous operations such as pressing with. Further, even if there is a display character such as “ON” or “OFF” displayed on the surface of the operation unit 5, it can be easily identified by the slit 4c, and further, the unevenness of the slit 4c can be fingered. It can also be used as a slip stopper when moving the cover 4.

Reference numeral 7 is a panel to which the waveform switch 1 is attached. On the other hand, normally, the cover 4 does not come off from the switch front plate 2, but when the cover 4 becomes unnecessary, that is, when the cover 4 becomes an obstacle in the switch operation, the both side surfaces 4b, 4b are expanded and guided. By removing the piece 4a from the guide groove 3, the cover 4 can be easily removed from the switch front plate 2. On the contrary, since the cover 4 can be easily attached in the same manner, the versatility of the small switch is not lost.

As another embodiment, the slit 4c may be omitted, or a plurality of protrusions may be provided instead of the slit 4c so as to exert the function of preventing slippage.

[0012]

[Effect of the device]

 As described above, according to the waveform switch with erroneous operation prevention cover of the present invention, since the cover that covers half of the operating part is slid on the switch surface, not only erroneous operation can be prevented, but also the additional parts are only the cover. Well, it has a simple structure and can be manufactured at low cost, and it does not lose the advantages of its size and versatility as a small switch.
