PROBLEM TO BE SOLVED: To provide a switch capable of preventing bridges among fixed contacts due to worn powder. SOLUTION: Brushes 31 functioning as a wiper member sliding on and contacting with an insulating substrate 21 are arranged at the front side and back side of the movable contact 30 in sliding direction thereof.Therefore, the bridges are broken by the brush 31 and insulating failures among fixed contacts 22 to 25 are surely avoided even if the bridges are about to be formed among the fixed contacts 22 to 25 embedded on the substrate 21 by the worn powder and a lubricating agent.
