Abstract
A rotary manipulation type electronic component includes a space formed by a case. A base houses a rotating body holding a resilient contact as a movable element. A comb-like contact is formed as a fixed element. A first bushing in the case and a second bushing in the base rotatably support a rotating shaft that rotates together with the rotating body. An inner bottom face of a cap-shaped knob is secured onto an end of the rotating shaft so that the knob receives a barrel portion, which supports the rotating shaft as a portion of the case.
