PROBLEM TO BE SOLVED: To improve contact reliability of a contact point by making a movable contact and a fixed contact relatively greatly slide at opening and closing. SOLUTION: A coupling neck part to have a narrow width is installed at a coupling part of a U-shape support frame formed at the tip part of a common terminal plate in order to support a movable member of a switch constituted of a movable contactor and an operation lever or the like with the common terminal plate, and by exposing it on an insulating base in which this coupling neck part supports a fixed terminal plate, and by reducing rigidity of the support frame, at an opening and closing operation, an insulating film formed on a contact surface is removed by greatly sliding the movable contact on the fixed contact.
