The sixth substrate 32a has a sixth sensing area S6 corresponding to the fifth sensing area S5, and the third conductive layer is connected to the sixth substrate 32a and disposed in the sixth sensing area S6. The third spacer layer connects the fifth substrate 31a and the sixth substrate 32a, and has a third spacer region, so that the third resistive layer 33a and the third conductive layer are spaced apart and will not contact each other.

The fifth substrate 31a has a seventh extension 311a located outside the sixth substrate 32a at the fourth connection end E4, and the third resistive layer 33a crosses the third spacer layer and extends to the seventh extension 311a. The seventh extension section 311a is derived from a seventh body section of the fourth connecting end E4 (the figure shows the lower element covered by the eighth body section 322a) along the first lateral direction DS1 (Marked in the fifth figure) and then extend along the second extension direction D2 (marked in the fifth figure).

The sixth substrate 32a has an eighth extension section 321a at the fourth connection end E4, and the third conductive layer and the third spacer layer extend together to the eighth extension section 321a. The eighth extension section 321a extends from an eighth body section 322a of the fourth connecting end E4 along the second lateral direction DS2 (marked in the fifth figure) and then extends along the second extension direction D2 (marked in the fifth figure) Out.

In the same overlapping relationship as the first embodiment, the eighth extension section 321a is located above the sixth extension section 222a, and the seventh extension section 311a is located below the fifth extension section 212a. Therefore, the thickness after being laminated is still substantially the same as the thickness of a single component. It should be noted that in this embodiment, the first resistance element 1, the second resistance element 2a and the third resistance element 3a can be overlapped by using the conductive adhesive layer L as in the first embodiment to make the first resistance element 1. The second resistance component 2a and the third resistance component 3a are glued to each other and connected.

Finally, please refer to Figures 12 and 13, where Figure 12 is a three-dimensional exploded view of the tandem position sensor provided by the third embodiment of the present invention; and Figure 13 is The three-dimensional view of the tandem position sensor provided by the third embodiment of the present invention is shown. As shown in the figure, a tandem position sensor 100b includes a first resistance element 1b, a second resistance element 2b, a third resistance element 3b, at least one riveting element 4b, and at least one second riveting element 5b.

The first resistance component 1b, the second resistance component 2b, and the third resistance component 3b are similar in structure to the first and second embodiments. They all have two substrates (the first substrate and the second substrate, the third substrate and the fourth substrate). Substrate or fifth substrate and sixth substrate), a resistive layer (first resistive layer, second resistive layer or third resistive layer), one conductive layer (first conductive layer, second conductive layer or third conductive layer) And a spacer layer (the first spacer layer, the second spacer layer or the third spacer layer).

The main difference is that the first resistance component 1b, the second resistance component 2b, and the third resistance component 3b do not have extension sections (the first extension section and the second extension section, the third extension section and the fourth extension section or the fifth extension section). Paragraph and sixth extension). After the second resistance component 2b is partially stacked and connected to the first resistance component 1b, and the third resistance component 3b is partially stacked and connected to the second resistance component 2b, the first resistance component is connected by the riveting element 4b and the second riveting element 5b 1b. The second resistance component 2b and the third resistance component 3b are riveted in sequence. After riveting, the first resistive layer is connected in series to the second resistive layer by the riveting element 4b, and the second resistive layer is also connected in series to the third resistive layer by the second riveting element 5b. Similarly, the conductive layers are also connected to the third resistive layer by riveting elements 4b. It is connected in series with the second riveting element 5b. The riveting element 4b and the second riveting element 5b can be rivets.

In this embodiment, because the first resistance component 1b, the second resistance component 2b, and the third resistance component 3b do not have extensions, the width of the series-connected position sensor 100b is smaller than that of the series in the first embodiment. The connection type position sensor 100 is the same as the series connection type position sensor 100a in the second embodiment. The tandem position sensor 100b may also include a second conductive adhesive layer, instead of the second riveting element 5b, to bond and conduct the second resistance element 2b and the third resistance component 3b. The second conductive adhesive layer is substantially the same as the conductive adhesive layer L in the first embodiment, and has the functions of physical connection and electrical connection at the same time.

The conductive layers of the above three embodiments usually contain silver paint, while the resistive layers of the above three embodiments usually contain carbon powder. Part of the resistive layer or part of the conductive layer spans the spacer layer to the extension section, but the thickness of the resistive layer and the conductive layer is very small compared to the overall thickness, only about 10 microns, so it does not affect the substantially same thickness.

In addition, the riveting element 4b and the second riveting element 5b can also replace the conductive adhesive layer L in the first embodiment, so that the first resistance element 1 and the second resistance element 2 can be riveted in sequence. The riveting element 4b and the second riveting element 5b can also be substituted to the second embodiment, whereby the first resistance element 1, the second resistance element 2a, and the third resistance element 3a can be riveted in sequence. The conductive adhesive layer L can also replace the riveting element 4b in this embodiment.
