Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0022] Such as figure 1 As shown, the moving contact structure of the present invention includes a movable part (1), a support part (2), and a fixed shaft (3). A shaft hole (4) is opened on the movable part (1) and the support part (2), and the fixed shaft (3) passes through the shaft hole (4), and the movable part (1) and the support part (2) are stacked and connected to the Together, make the two in close contact through the upper and lower sides. The electrical connection between the movable part (1) and the support part (2) is realized by close contact between the adjacent upper and lower surfaces, such as figure 1 The shaded part where the middle movable part (1) overlaps with the support part (2).
[0023] Such as figure 2 As shown, the movable part (1) of the present invention is a square, the four corners are arc-shaped chamfers (5), and the shaft hole (4...
