A switch comprises: a base (10) which has a flat circular recess (11) formed in the upper surface of the base (10) and which has center stationary contact points (15, 16, 16b, 17, 17b) disposed on the inner surface of the flat circular recess (11); a spring body (20) which has a bellows shape formed by repeating a reference form section (23) and which is disposed in an annular shape in the flat circular recess (11) in the base (10); and an operation body (30) which has a pivoting section (31) fitted in a pivotable manner in the flat circular recess (11) in the base (10) and which has a protrusion (34) for operation provided in a protruding manner on the inward facing surface of the pivoting section (31). The pivoting of the operation body (30) causes the protrusion (34) for operation to press on and compress the ends (21, 22) of the spring body (20), and this enables the selection of a contact point.
