PROBLEM TO BE SOLVED: To provide a compact switch in which a contact can instantaneously be opened and closed while the number of components and assembling man-hour are decreased. SOLUTION: The switch includes a support terminal (21) which is assembled in a base (10); a movable contact piece (30) which is formed of a belt-like electroconductive material bent into a substantial J-shape in cross section, the movable contact piece including a movable contact (31) provided at one end thereof, an intermediate portion of the movable contact piece supported by a turning support (24) of the support terminal (21) so as to be turnable; a plunger (40) which is accommodated in an internal space while being able to be vertically moved, the internal space formed by fitting a housing (60) in the base (10); and a coil spring (50) which is supported by the plunger (40) so as to be turnable. The plunger (40) is slid while being vertically moved to press-contact with one end (51) of the coil spring (50) to the other end edge of the movable contact piece (30), whereby the movable contact piece (30) is reversed to bring the movable contact (31) into contact with a fixed contact (26) or to separate the movable contact (31) from the fixed contact (26).
