Claims

[Scope of utility model registration request]

(1) A movable contact piece is pivotally supported on a rising piece of a common terminal provided on a switch base, and an actuating piece and the movable contact piece are provided at a position opposite to the movable contact piece, sandwiching the rising piece. By mounting a tension coil spring between the movable contact piece and the tension coil spring, the actuating piece or the tension coil spring itself is pressed by an external force and the movable contact piece is reversed via the tension coil spring. A switch mechanism for switching fixed contacts to be contacted, characterized in that an arc shielding portion is provided between a hook portion of a tension coil spring attached to the movable contact piece and a contact portion between the movable contact piece and the fixed contact. switch mechanism.

(2) The switch mechanism according to claim 1, further characterized in that the arc shielding portion is a protrusion provided from the movable contact piece on either or both of the upper and lower sides thereof. .

(3) The switch mechanism according to claim 1, further characterized in that the arc deflection portion is a protrusion provided from the fixed contact terminal toward the movable contact piece. .
