PROBLEM TO BE SOLVED: To provide a compact, long-life air switch without increasing costs. SOLUTION: An arc-extinguishing chamber 10 of the air switch is formed nearly in an L shape, an arc-extinguishing chamber 10a extended in a horizontal direction is arranged on one side, and a fixing contact 5 is arranged at a lower section on the other side. Additionally, the shape of a tip in a movable contact 8 is formed in a shape tilted so that an outer periphery is long and an inner periphery is short and the sectional shape of an upper end at the arc-extinguishing chamber 10d formed by an insulating material is set to be in a triangular shape using the upper end as a vertex.
