In a drawer type circuit breaker of the invention, when a first contact is clockwise pivoted by a switching mechanism, the contact tip of the first contact and the contact tip of a second contact are touched, and when the first contact is further clockwise pivoted, the second contact is counterclockwise pivoted against the elastic force of a spring to secure a predetermined contact pressure and a predetermined wiping stroke. A first drawer contact clamps the outer circumferential portion of the first contact and a first external connection terminal together by the elastic force of a spring to establish connection between the first contact and the first external connection terminal. A second drawer contact clamps the outer circumferential portion of the second contact and a second external connection terminal together by the elastic force of another spring to establish connection between the second contact and the second external connection terminal.
