PROBLEM TO BE SOLVED: To provide a switch consisting of an insulating base fitted with stationary contact, a movable contact spring in the form of a coned disc spring, and a pressing means such as a push button, etc., wherein a wire is embedded in the base in such a way as partially exposed at the inner surface of a bottom plate, and the exposed portion is allowed to serve as stationary contact while the part protruded outside the base is used as a terminal. SOLUTION: A movable contact spring 3 in the form of a coned disc spring formed by protruding the center of a circular spring sheet into a spherical shape is provided mating with a stationary contact 2 formed exposed at the inner surface of the bottom plate 1a of an insulating base 1 in such a way that the spherical portion 3a of the spring 3 is facing down or up and a pressing means 4 such as a push button, etc., is installed on the movable contact spring 3 so that the switch is constructued, wherein a wire W is embedded in the bottom plate 1a of the base 1 in such a way as straight, curved, or crossing above and below, and part of the wire W is exposed at the inner surface of the bottom plate 1a linearly to serve as the stationary contact 2, otherwise part of the wire W is curved into a projection 2b and only its top is exposed at the inner surface of the bottom plate 1a so as to serve as the stationary contact 2, and the wire portion protruding outside the base 1 is used as a terminal 2a.
