PURPOSE: A compact high-frequency use switch of a high productivity is provided to obtain the desired high-frequency characteristic. CONSTITUTION: Insulating walls(14, 15) are arranged between fixed contacts(21a, 23a) that face a movable contactor(51b) while being able to come in and out of contact with it and a shield plate(24) positioned on the back surface side of the fixed contacts(21a, 23a). A dielectric is arranged between a fixed contact that faces a movable contact while being able to come in and out of contact with it and a shield member is located in the vicinity of the fixed contact. A plurality of movable contactors that reciprocate in the direction of thickness thereof on the basis of excitation and non excitation of an electromagnet block are brought in and out of contact alternately with a common fixed contact and a normally-open fixed contact and with the common fixed contact and a normally-closed fixed contact so as to open and close a high-frequency current circuit.
