Claims

[Scope of utility model registration request]

A common terminal and first and second fixed terminals are provided in parallel with the common terminal and in series with each other, while the slider is branched into first and second contact pieces and is connected to the first contact piece. In a contact switching mechanism of a switch in which the piece is always in contact with the common terminal and the second contact piece is switched into contact with the first and second fixed terminals, the tip of the second contact piece is connected to at least the first and second fixed terminals. A notch is provided at the end of the first fixed terminal on the side that branches into one contact point of the second contact piece, and a second fixed terminal on the side that contacts the other contact point of the second contact piece. A contact switching mechanism for a switch, characterized in that a notch is provided at the end of a fixed terminal.
