PROBLEM TO BE SOLVED: To provide a switch device wherein maintenance of workability and dimensional precision is easy and simple, countermeasures for cost saving is enabled and reliability of contact part can be improved by using a round wire material as a spring material of contact point mechanism in a structure of quick operating type switch device. SOLUTION: A support arm 7 whose one end is locked to a conductor plate 8 and another end is locked to the central terminal 3, and a spring member 10 which is bent and arranged and installed between the conductor plate 8 and the central terminal 3 and which movable supports the conductor plate 8 at the central terminal 3 are formed by the round wire material having a spring property, then the support arm 7, the conductor plate 8 to which the spring member 10 is locked, and a locking part to the central terminal 3 are formed in an arc face-form.
