な構造となっている。FIG. 4 is a sectional side view showing another embodiment of the sliding fixed contact 80 of the present invention. In FIG. 4, the plurality of sliding contact pieces 20 are led out from the holding cylinder 10 in a cylindrical shape, as in the above-described embodiment. However, in this embodiment, the holding cylinder 10 is made of a conductive material. This sliding contact piece 20
The inner surface of one end (the left end in FIG. 4) of the is formed with a convex surface 20a that contacts the movable contact 7. Further, as shown in FIG. 4, the holding cylinder 10 and the sliding contact piece are fixed by the bolt 30.
The surface of the substrate 40 for fixing the 20 is an inclined surface with respect to the direction in which the sliding contact piece 20 is led out. The other end of the sliding contact piece 20 is fixed to the holding cylinder 10 and the substrate 40 with one type of bolt 30. Therefore, since the sliding fixed contact 80 of this embodiment is assembled with one type of bolt 30, the assembly process is reduced and the structure is simple and easy to manufacture.
