[0004] Although the switch can connect the test antenna to testers of different frequency bands and can quickly switch between different testers, in actual use, due to the particularity of its structure (raised components are provided on the outer surface, top and bottom), it is not easy to arrange and fix.

In addition, during long-term use, pollutants such as dust, water vapor, and organic matter in the environment may enter the cavity through the gaps on the outer surface of the switch, and randomly adhere to the connecting piece and the second conductive piece, which increases the contact resistance and increases wear, and easily causes poor contact between the connecting piece and the second conductive piece. Therefore, improvements are proposed. Utility Model Content
