Claims

[Scope of Claim for Utility Model Registration] (1) A movable contactor consisting of a columnar body and a spherical tip provided at one end of the columnar body and having a radius larger than that of the columnar body; When each of the divided members is in close contact with each other and is divided into at least two parts, the upper end is the minimum radius part having the same radius as the columnar body of the movable contact with the axis as the center, and the tip of the movable contact is moved toward the lower end. a fixed contact having a cavity having a radius larger than the minimum radius of the upper end so as to engage with the spherical part; a conductor having an engaging part for engaging with the lower end of the fixed contact; A contact device for a switch, comprising: a spring that unites the at least two divided fixed contacts with a predetermined force and further urges the fixed contacts to maintain engagement with the conductor. (2) The spring is formed by bending a plate spring material into a C-shape, and the open portion is formed by at least one of the fixed contacts.
2. The contact device for a switch according to claim 1, wherein the direction of the groove for dividing the switch coincides with the direction of the groove.
