Detailed ways

Reference will now be made to embodiments of the disclosure, one or more examples of which are illustrated in the accompanying drawings. The examples are provided by way of illustration of the disclosure and are not intended as limitations of the disclosure. For example, features illustrated or described as part of one embodiment may be used in another embodiment to yield a further embodiment. This disclosure is intended to embrace these and other modifications and variations that are within the scope and spirit of this disclosure.

FIG. 1 is an exploded view of a switchgear according to one embodiment of the present disclosure. The switchgear comprises a mounting panel 1 for fixing to a surface, such as a wall, on which said switchgear is mounted. At least one switch module 2 (four in FIG. 1 ) can be installed on the installation panel 1 in any arrangement. The switch module 2 can be connected to a working circuit to control the on and off of the working circuit, for example, to control the on and off of a lamp or a power socket. The switch module 2 in FIG. 1 is a button switch module, and each button switch module has a switch button 21 . The characteristic of this push-button switch module is that when the button is pressed for the first time, the switch module is closed or opened, and when the button is pressed again, the switch module is opened or closed. A through hole 11 is provided at a position corresponding to each switch module 2 on the installation panel 1 , and when the switch module 2 is installed on the installation panel 1 , the switch button 21 extends into the through hole 11 .

An operation panel 3 is movably connected to the installation panel 1 and can be driven to operate each of the switch modules 2 respectively. In the embodiment shown in FIG. 1 , only one integral operation panel 3 is provided. The operation panel 3 can be pivotally connected to the center of the installation panel 1, so that it can swing in various directions around the pivot and respectively press the switch buttons 21 of a plurality of switch modules 2 located in various directions around the pivot to operate the respective The switch module 2 is closed or closed. Of course, a reset mechanism such as a spring should also be provided so that the operation panel 3 returns to a balance position parallel to the installation panel 1 after each pivoting and swinging operation relative to the installation panel 1 to facilitate the next operation.

An indicator block 4 is detachably sheathed on the switch button 21 of each switch module 2 to indicate the function of each switch module 2 . The indicating block 4 is arranged at a position between the switch button 21 and the operation panel 3 . The operation panel 3 may just touch the indicating block 4 or be a little distance away from the indicating block 4 (see FIGS. 3 and 4 ). In this way, when the operation panel 3 is pressed, the operation panel 3 will drive the indicating block 4 and the corresponding switch button 21 to move in the through hole 11 to operate the switch module 2 .

An indication block 4 according to an embodiment of the present disclosure is shown in FIG. 2 . As shown in FIG. 2 , the indicator block 4 has two end surfaces and a side surface between the two end surfaces. There is a blind hole 41 on one of the end faces, and the shape of the blind hole 41 can match the shape of the switch button 21. For example, the blind hole 41 in FIG. 2 is circular to match the circular switch button 21 in FIG. 1 , but it doesn't have to be. However, it should be ensured that the size of the blind hole 41 is slightly larger than the size of the switch button 21 . There are several protrusions 42 extending along the axial direction of the blind hole 41 on the sidewall of the blind hole 41 . As shown in Figures 3-4, when the indicator block 4 is slidably sleeved on the switch button 21, the switch button 21 is inserted into the blind hole 41, engages with the protrusion 42 and slightly squeezes the protrusion 42 to achieve interference Cooperate. This interference fit prevents the indication block 4 from falling off from the switch button 21 . Since only a few thin protrusions 42 are in interference fit with the switch button 21, and most of the sides of the switch button 21 are not in contact with the indicator block 4, therefore, no large resistance will be encountered when installing and dismounting the indicator block 4 , thus facilitating the installation and removal of the indicating block 4 . Of course, under the condition that both the switch button 21 and the blind hole 41 in the indicator block 4 have high dimensional accuracy, the protrusion 42 may not be provided, and the blind hole 41 of the indicator block 4 is directly placed on the switch button 21 To achieve interference fit, but at this time the size of the blind hole 41 should be exactly equal to or slightly smaller than the size of the switch button 21 .

In one embodiment, an operating part may be provided on the indicating block 4 so that when the indicating block 4 is to be replaced or disassembled, the indicating block 4 is easily operated by fingers or tools to separate from the switch button 21 . For example, in FIG. 2 , a groove 43 is provided on the side of the indicating block 4 as an operation part. Human fingers or a tool such as a screwdriver can easily dig into the groove 43 to separate the indicator block 4 from the switch button 21 .

In one embodiment, the shape of the end surface of the indicating block 4 can be configured so that the indicating block 4 is suitable for moving in the through hole 11 on the installation panel 1 along the axial direction of the through hole 11, but not suitable for Rotate in the through hole 11 to ensure that the indicator block can be driven by the operation panel 3 to operate the switch button 21 without rotating to change the orientation of the mark on the indicator block 4 . For this reason, the shape of the end surface of the indicating block 4 should be smaller than the size of the through hole 11, and can have a shape matching the through hole 11, but should avoid using a circular shape to prevent rotation. As shown in FIGS. 1-2 , for example, when the through hole 11 is square, the end face of the indicating block 4 may also be square, so that the square indicating block 4 cannot rotate in the square through hole 11 .

Various marks 44 can be printed on the end face of the indicator block 4 without blind holes 41 to indicate the function of the switch module 2 corresponding to the indicator block 4, for example, to indicate which lamp or power socket the switch module 2 is used to control. . The mark 44 can be any pattern, character or combination thereof. The mark 44 can be formed on the end surface of the opaque indicator block 4 as a light-transmitting part, or the mark 44 can be formed on the end surface of the light-transmitting indicator block 4 as an opaque part. A lighting device is also provided in the switch button 21 . The indicator block 4 is irradiated by light from the light emitting device, and the light transmitted from the light-transmitting portion on the end surface of the indicator block 4 is projected onto the operation panel 3 facing the indicator block 4 , thereby projecting a marked pattern on the operation panel 3 . Depending on the way indicia is formed on the indicator block 4, the projected pattern of the indicia may be partly bright and dark around the mark (ie, positive), or partly dark and light around the mark (ie, negative). The operation panel 3 is made of thinner material with partial light transmission capability, such as thin plastic. Normally, the operation panel 3 is opaque. But when the light of the light-emitting device in the switch button 21 very close to the operation panel 3 is projected on the operation panel 3 through the light-transmitting part in the indicating block 4, the projected light is enough to pass through the operation panel 3, thereby from the operation Looking at the side of the panel 3 facing away from the indicating block 4 , one can see the markings in the form of positive or negative characters formed by the light projected on the operation panel 3 . In this way, the user can clearly see the corresponding marks at different positions on the operation panel 3 , and know that pressing the position of each mark on the operation panel 3 can operate the corresponding switch module 2 to realize the function indicated by the marks.

For Yang Wen mark, can provide the indicator block 4 of overall opacity, and engrave the mark pattern of hollow out on its end face, make mark part light-transmitting; Also can provide the end face of light-transmitting indicator block 4, then spray or paint on it Cover the area other than the mark with paper to expose only the marked portion. And for the negative mark, can directly print the opaque marking pattern on the end face of the light-transmitting indicating block 4 .

The light emitting device can be kept in a constant light state so that the user can see the mark on the operation panel 3 at any time, which is advantageous when using the mark on the indicator block 4 to indicate which electrical equipment is controlled by the operation panel. However, when the switchgear has only one switch module 2, and the sign is used to indicate the switch state of the known electrical equipment, the lighting device can only light up when the switch module 2 is closed or turned off, by Therefore, the lighting or extinguishing of the mark on the operation panel 3 can indicate the status of the corresponding electrical equipment.

In the case that the marking needs to be kept bright, it is not necessary to provide light through a separate light emitting device. Instead, the indicator block 4 may have self-luminous markings, such as fluorescent markings. And the light of the self-luminous mark can be seen through the operation panel 3 . This may be more advantageous in typically darker environments since self-illumination is relatively weak.

Since the indicating block 4 is hidden behind the operation panel 3 and is invisible to the user, the surface of the operation panel 3 appears very clean and beautiful. When the sign is illuminated, the illuminated sign pattern clearly appears on the operation panel, making this switchgear appear very high-end.

In another embodiment, the indicating block 4 can also be arranged at other positions between the switch module 2 and the operation panel 3 . For example, the indicating block 4 can be detachably installed on the side of the operation panel 3 facing the switch module 2 . For example, by providing a protrusion or a receiving groove on the side of the operation panel 3 facing the switch module 2 , the indicating block 4 can be detachably fitted on the protrusion or in the receiving groove. In a switchgear that uses one operation panel 3 to control multiple switch modules 2, when it is necessary to indicate a certain switch module 2 through the mark on the indicator block 4, it is still necessary to place the indicator block 4 on the side of the operation panel 3. The location corresponds to the location of the switch module to provide an accurate indication. But the indicator block 4 can be aligned with the switch button 21 or not, that is, the operation panel can drive the switch button 21 through the indicator block 4 or directly drive the switch button 21 without the indicator block 4 . In the case that the indicating block 4 is not aligned with the switch button 21 , it may be necessary to arrange a light emitting device on the operation panel 3 at a position aligned with the indicating block 4 to illuminate the indicating block.

Although the switch device according to the present disclosure has been described above based on a push button switch module, it should be understood that the switch device of the present disclosure is also applicable to other types of switch modules. For example, for the rocker switch module, it is advantageous to arrange the indicator block 4 on the side of the operation panel 3 facing the switch module, because the rocker switch module does not have a switch button, so it is not convenient to place the switch on the rocker switch. Set indicator block 4 on the module.

In addition, although only one operation panel 3 is provided in the embodiment described above, it should be understood that more than one operation panel 3 may be provided for the switch device, and each operation panel 3 is used to control one or more switch modules. In the case of providing multiple operation panels 3 , one or more indication blocks 4 may be provided for each operation panel 3 to indicate the function or state corresponding to one or more keys of the operation panel 3 .

The operation panel 3 in the switchgears of the above-mentioned embodiments is preferably detachable conveniently. When the indicator mark needs to be replaced after changing the controlled electrical equipment of the switchgear, the operation panel 3 is detached earlier, and then the indicating block 4 is taken off from the switch button 21 or the operation panel 3, and then a new one with the same The indication block 4 of the mark corresponding to the electrical equipment controlled, and then the operation panel 3 is loaded onto. In this way, when the mark is turned on again, a new mark is displayed on the operation panel. If the mark on the indicating block 4 is formed by a sticker pasted on the indicating block 4, the indicating block 4 may not be disassembled and replaced, but only the original sticker on the indicating block 4 is torn off, and the sticker with a new mark is re-pasted. Can. Thus, the markings for the switchgear can be replaced conveniently and at low cost without replacing the operation panel with a new one, and without damaging or soiling the appearance of the original operation panel.

It should be understood that the switchgear of the present invention is suitable for being installed in a groove on a wall, a panel, etc., for use in domestic, commercial or industrial occasions. Each switch module in the switch device can be used to respectively control lighting circuits, power supplies, electrical equipment and the like.

It should be noted that the above-mentioned embodiments are given to describe the principle of the present utility model, rather than limit its scope; and it should be understood that modifications and variations, which will be readily understood by those skilled in the art. Such modifications and variations are considered to be within the scope of the present invention and the appended claims. The protection scope of the utility model is defined by the appended claims. Furthermore, any reference signs in the claims should not be construed as limiting the claims. Use of the verb "comprise" and its conjugations does not exclude the presence of elements or steps other than those stated in a claim. The indefinite article "a" or "an" preceding an element or step does not exclude the presence of a plurality of such elements or steps.
