In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It is to be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present application and simplify description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the present application.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

With the advancement of society and the development of technology, a touch control switch is gradually used to control a lamp or other electrical appliances.

The conventional touch control switch is generally provided with an induction piece on the back of the touch panel, and then the induction piece is connected with a main control panel in the control switch through a power line.

However, because the experience and texture requirements of users on the control switch are higher and higher at present, the touch panel of many control switches is made of metal materials, and the metal materials generally have conductive properties, so when the sensing piece is arranged on the back of the touch panel, if the main control panel or the sensing piece connected with the sensing piece is short-circuited, the situation of electric leakage easily occurs, and potential safety hazards exist for the use of users.

In order to prevent potential safety hazards, the application provides a jump layer touch structure which can be applied to a control switch.

The jump layer touch structure comprises a touch panel, an insulating piece and an induction piece, wherein the insulating piece is arranged between the touch panel and the induction piece, and plays an insulating role between the induction piece and the touch panel. When the induction piece is short-circuited or leaked, current cannot be conducted to the touch pad under the action of the insulating piece, and electric shock of a user can be well prevented.

Referring to fig. 1, a jump layer touch structure includes a touch pad 100, an insulator 200, and a sensing patch 300 according to some embodiments of the present application. The touch pad 100 includes a first upper surface and a first lower surface disposed opposite to each other, the first upper surface being a touch surface contacted by a user. The insulating member 200 includes a second upper surface and a second lower surface disposed opposite to each other, the second upper surface being connected to the first lower surface. The sensing sheet 300 is disposed on the second lower surface, and the thickness of the insulating member 200 is smaller than the sensing distance of the sensing sheet 300 to ensure that the sensing sheet 300 can sense the touch signal of the touch panel 100.

It can be seen that, since the insulating member 200 is disposed between the sensing piece 300 and the touch panel 100, and the thickness of the insulating member 200 is smaller than the sensing distance of the sensing piece 300, the insulating member 200 can perform an insulating function and the sensing of the touch signal by the sensing piece 300 is not affected.

The sensing sensitivity of the sensing piece 300 is also related to the sensing distance, so the sensitivity of the sensing piece 300 can be adjusted by changing the thickness of the insulating member 200.

The touch pad 100 may be made of metal, such as iron, stainless steel, aluminum, copper, or aluminum alloy.

The sensing sheet 300 may employ a capacitive sensing sheet 300.

Additionally, in some embodiments, the insulator 200 may be a PCB board such as that of fig. 2, while in order to ensure the sensitivity of the sensing sheet 300, the thickness of the PCB board may be 0.8mm to 1.5mm, for example, the thickness of the PCB board may be 0.8mm,1.0mm,1.2mm, or 1.5mm.

It can be appreciated that the PCB itself has an insulating property, and the PCB also has a second upper surface and a second lower surface of the insulating member 200, so that the sensing piece 300 is disposed on the second lower surface of the PCB, that is, the back surface of the PCB is disposed, so that the sensing piece 300 does not directly contact with the touch pad 100, and meanwhile, the PCB is just convenient for the installation of the sensing piece 300, so that the sensing piece 300 can be directly welded on the PCB, and no connection of power lines is required, so that the operation of the sensing piece 300 is more stable.

When the jump layer touch structure is arranged on the control switch, the PCB can be electrically connected with the main board in the control switch.

Of course, in other embodiments, the insulating member may be an insulating material such as a plastic plate, rubber, glass, or silicone. At this time, the sensing piece can be connected with the touch chip of the main board in the control switch through the power line.

In addition, the application also provides a control switch, which comprises the jump layer touch structure in the embodiment.

In some embodiments, the control switch may further comprise a master control board. When the insulating piece in the jump layer touch structure is a PCB, the main control board can be connected with the PCB. When the insulating piece in the jump layer touch structure is a non-PCB (printed circuit board), namely, an insulating material such as a plastic plate, rubber, glass or silica gel is adopted, the main control board can be electrically connected with the induction piece through a power line.

The foregoing description of the preferred embodiment of the present utility model is not intended to limit the utility model to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the utility model.
