Abstract (en)

[origin: JPH02117024A] PURPOSE: To reduce the cost and resistance by providing a contact means and a substantially circular contact member rotatably connected to this contact means. CONSTITUTION: A contact arm 18 having a circular contact part 20 is rotated around an axial line 22 when contacts 10, 12 are opened and closed. A contact member assembly 24 cooperates with the circular contact part 20 in order to complete the current-carrying passage from a terminal 16 to the contact arm 18. The contact member assembly 24 has two contact plates 26, 28 to be engaged with the circular contact part 20, the contact plate 26 has one or a plurality of end part 30 having a flat surface 32 so as to make contact with the circumference of the circular contact part 20, and the contact plate 28 has two end parts 34 having flat surfaces 38 so as to make contact with the circumference of the circular contact part 20. Namely, three contact positions 40 is provided in order to form a current path between the contact plates 26, 28 and the contact arm 18. Thus, a rotating contact part structure having a low electric resistance, a low manufacturing cost, and high reliability can be provided.
