Therefore, the existing isolating switches generally have two sets of shells with different outlet directions, thereby improving the diversity of its products, one of which is the upper outlet and the other is the lower outlet. At the same time, different outlet directions make the structure of the conductive sheet inside the isolating switch different. However, a variety of different shells undoubtedly increase the production cost, and it is easy to make the commonality of parts between the same products not high. Utility Model Content
