Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a switch cover, and particularly to a switch cover suitable for use in a slide switch used in general electronic equipment, etc., for switching between two power supply voltage systems.

[Prior Art] Generally, electronic devices are required to operate under different power supply voltage specifications. However, the power supply voltage specifications differ significantly between Japan and other countries, and there are significant cost and technical constraints in creating a product that can operate with all power supply voltage specifications.

Conventionally, therefore, countermeasures have been taken, such as preparing products with the same main circuit configuration but different only in the power supply section for each power supply voltage specification, or providing each product with a power supply voltage changeover switch.

[Problem that the invention aims to solve] However, when preparing products that differ only in power supply voltage specifications, the number of product types increases, which increases the burden on production management and leads to increased costs.

Therefore, a method of installing a power supply voltage changeover switch is generally adopted, but although it can reduce the burden on production management, it is easy to change the power supply voltage setting due to unexpected external force or carelessness of the user. This may cause equipment damage or accidents.

[Means for Solving the Problems] In order to solve the problems of the prior art described above, the present invention provides a switch cover that covers two power supply voltage changeover switches mounted on a predetermined casing surface of an electronic device. a first window and a second window are provided;
The window is provided to selectively expose one of the two power supply voltage set value displays displayed on the casing surface when the front or back side of the switch cover is attached to a predetermined position. Window 2 shows that when the power supply voltage selector switch is set correctly according to the power supply voltage setting value display, the operating section of the switch is hidden, and when it is set incorrectly, the operating section of the switch is hidden. It is provided so as to be exposed so that the power supply voltage changeover switch can be reset to correspond correctly to the power supply voltage set value display.

[Function] When the switch cover is attached on its front side, for example, on the housing surface of an electronic device so that the first window exposes the desired power supply voltage set value display, the power supply voltage changeover switch corresponds to the power supply voltage specified above. If the switch is set in this position, the operating section of the switch will not be exposed through the second window, but will be covered. However, when set in error, the switch is exposed in the second window and can be reset to the correct position.

Also, by attaching the back side of the switch cover, the first window exposes a separate line voltage setpoint display, and the second window correspondingly covers a correctly set switch and displays this setpoint display. A similar effect can be exerted on

[Embodiments] Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIGS. 2a and 3a show a power supply voltage changeover switch section of an electronic device embodying the present invention. The power supply voltage change-over switch is fixed with a screw 8 so that a switch lever 2 serving as a switch operating section is exposed from inside a window hole 7 of the electronic device and can change settings.

Further, near the power supply voltage changeover switch of the electronic device, two power supply voltage setting values with which the electronic device can operate are displayed, for example, AC100/120V and AC220/240V.

Figures 2a and 3a show that the power supply voltages at which this electronic device should operate are 100/120V AC and 120V AC, respectively.
This shows the state set to AC220/240V.

FIG. 1 shows a switch cover 1 according to the present invention, for example, showing its front side, in which a first window 4 and a second window 5 are provided at predetermined positions. 3 is a screw hole for attaching a switch cover, and 6 is an escape hole for a mounting screw 8 of a power supply voltage changeover switch attached to an electronic device.

Therefore, when the front side of the switch cover 1 is attached to the top surface of the electronic device using screws 10 as shown in FIG.
AC100/120V can be seen.

At this time, as shown in Figure 2a, the power supply voltage selector switch displays the power supply voltage setting value AC100/120V
If the switch lever 2 is set at a position corresponding to the window 5, the switch lever 2 will not be exposed inside the window 5.

That is, the switch lever 2 is connected to the switch cover 1.
This prevents erroneous settings caused by external force or erroneous operation.

Here, if the power supply voltage selector switch is set to AC220/240V as shown in Figure 3a, the switch lever 2 will be exposed through the second window 5 as shown in Figure 4. . Therefore, it is possible to easily identify that the power supply voltage setting is incorrect, and also to change the setting to the correct setting by operating the switch lever 2.

Next, when the switch cover 1 is installed with the switch cover 1 facing backward, another power supply voltage display, AC220/240V, can be visually recognized from the first window 4 as shown in FIG. 3b.

At this time, if the power supply voltage selector switch is set to the correct position as shown in Figure 3b, the switch lever 2 will not be exposed in the second window 5, but as shown in Figure 2a. When the power supply voltage changeover switch is incorrectly set, the switch lever 2 is exposed through the second window 4 and can be reset to the correct position.

As explained above, by installing the switch cover with the front side or the back side up, the power supply voltage at which the electronic device should operate can be visually checked from the first window 4, and the power supply voltage setting value display On the other hand, when the setting of the power supply voltage changeover switch corresponds correctly, the switch lever 2 can be opened from the second window 5.
If the power supply voltage changeover switch is hidden and the setting of the power supply voltage changeover switch is incorrect, the switch lever 2 will be exposed through the second window 5, making it possible to easily set it again correctly.

[Effects of the invention] According to the invention, it is possible to easily check the correspondence between the setting of the power supply voltage selector switch and the display of the desired power supply voltage setting value, and if the setting of the switch is incorrect, it can be easily moved to the correct position. It is possible to reset the settings. In addition, when the settings are correctly made, incorrect settings due to external force, carelessness, etc. can be prevented.
