Rotary electronic component and method of manufacturing same

Abstract

Rotary electronic component of the invention has a contact board and an elastic contact. The contact board, including an annular contact having an arc-segmental portion split by a slit with a predetermined width and signaling contacts disposed at spaced positions and in electrical continuation with the arc-segmental portion, is fixed in a resin molding with the annular contact exposed on the top plane of the resin molding. The elastic contact slides on the contact board along the annular contact. In this rotary electronic component, a stress occurring when the annular contact is fixed by molding on to the contact board is relaxed owing to presence of the slit. Thus, a rotary electronic component generating an electric signal with a stabilized waveform over a long time can be obtained.
