In the figure, 4 is a fixed contact, 5 is a fixed conductor, 6 is a fixed contact, 7 is a movable contact, 8 is a movable conductor, 9 is a movable contact,
13A is an arc extinguishing chamber, 141 is a notch, 142 and 143 are wall surfaces, and 15A is a side plate. Note that the same reference numerals in each figure indicate the same parts.

Claims

[Claims for Utility Model Registration] 1. A fixed conductor having a fixed contact at one end, a movable conductor having a movable contact at one end opposite to the fixed contact and performing an opening/closing operation, and a movable conductor that is movable when the movable conductor opens/closes. An arc extinguishing chamber having an arc extinguishing plate formed with a notch through which the conductor passes,
A switch 2 in which a wall surface is formed on the arc-extinguishing plate along the longitudinal direction of the fixed conductor and facing the side surface of the fixed contact; the inner surface of the wall surface is formed flush with the side surface of the notch; A switch according to claim 1 of the utility model registration claim. 3. The switch according to claim 1 or 2 of the utility model registration claim, wherein the wall surface is formed by bending an arc-extinguishing plate.
