PROBLEM TO BE SOLVED: To enable improvement in durability by having contacts surely separated and contact point separation speed accelerated. SOLUTION: The switch is provided with a pair of contact plates 37a, 37b contact plates 37c, 37d supported to a housing 35 side and formed with a reversing spring capable of reversing and deforming with a spring force, a movable contact 65 fitted to each contact plate 37a, 37b, 37c, 37d in opposition feeding and breaking current by getting in and out of contact with each other, and contact members 39a, 39b supported to the housing 35 side and changing contact positions with each contact plate 37a, 37b, 37c, 37d according to an operation of a switching knob keeping in contact with each contact plate 37a, 37b, 37c, 37d. The contact members 39a, 39b change a contact position with each contact plate 37a, 37b, 37c, 37d and make the movable contact 65 in and out of contact by accessing and separating displacement due to the reversing deformation and its return of each contact plate 37a, 37b, 37c, 37d.
