A dial type switch mechanism is developed in which an installation space can be made as small as possible. In a dial type switch mechanism ( 10 ) furnished with a push type switch part provided in its center, and a dial switch part which operates a dial fitted around the push type switch part, there are provided: a substantially cylindrical dial knob ( 21 ), in the center of which a cavity is provided for the push type switch part to be installed; a ring-shaped joint ring ( 23 ), which is supported such that it can rotate freely relative to a front panel ( 6 ) and connects and rotates together with the dial knob ( 21 ); and a rotary bracket ( 24 ), which is joined to the joint ring ( 23 ), and in which a switch rotation shaft ( 24 b) that operates the dial type switch part is connected together with a ring-shaped member ( 24 a) via an arm ( 24 c).
