PROBLEM TO BE SOLVED: To provide a click switching type switching arrangement capable of simply performing switching and fixing of a clicking feeling produced in an operation switch. SOLUTION: A small click generating member 12 is combined with the inner peripheral surface of a yoke 9, and a large click generating member 16 is attached to the control shaft 10a of a dial knob 10 so as to be integrally rotatable. A plunger case 20 is attached to the control shaft 10b so as to be relatively rotatable, and a large click piece 23 and a small click piece 22 are attached to it. An electromagnet 29 is attached to the yoke 9, and a plunger magnetic body 31 which can be attracted to it is combined with the plunger case 20. A magnetic circuit produced in the yoke 9 is switched by attaching a permanent magnet 35 to the yoke 9 so as to cover it, and by switching among no excitation, excitation by reverse connection, and excitation by forward connection to make a coil magnetic field work together with the magnetic field of the permanent magnet 35, and the click of the dial knob 10 is thereby switched among three stages of the large click, the small click, and a fixed click.
