Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and in particular relates to a shift combination switch structure. Background Art

[0002] With the continuous development of the automotive industry, many OEMs have moved the shift control mechanism from the central console to the combination switch under the steering wheel, integrating the shift function on the combination switch, which not only saves space but also greatly reduces costs. However, most of the shift combination switch structures on the market currently use multiple Hall switches arranged in an array, and use magnets to trigger any Hall switch to achieve the shift function. However, since the magnet has a large magnetic field, it is easy for the magnet to accidentally touch adjacent Hall switches at the same time when shifting, resulting in low shift accuracy and affecting the shift effect, which will have a certain impact on quality stability.
