PROBLEM TO BE SOLVED: To provide a circuit switching coaxial connector capable of simply performing switching a frequency band cut without having to disconnect an electronic apparatus such as a serial unit. SOLUTION: An external shell 11 of a coaxial connector 3 is formed into cylindrical shape, and an insulator 12 and an insulator 13 are slidably installed in its inside. Inside the external shell 11, lateral slots 15a, 15b are formed in the inside peripheral surface on its front end side, and longitudinal slots 16 to combine the lateral slots 15a, 15b together. The insulator 12 is formed into a cylindrical shape, provided with a through hole 17 centering at its head, opened on the side opposite to the insulator 13, abutting its one end on the second insulator 13, provided with protrusions 19 on its outside surface and locked to the lateral slot 15a or 15b. A center contact 21 formed inside the insulator 13 is mounted to a printed circuit board 22 with its base projecting into a case 2. A push button switch 23 is installed on the printed circuit board 22 and the switch is operated by depressing its button 24 by the second insulator 13.
