コスト低減及び管理の簡素化を図ることができる。As described above, according to the present invention, the pair of terminal holders facing the circuit board can be coupled to each other by engaging the hook-shaped projections of the bosses inside the terminal holder with the engaging grooves. Parts such as screws protruding to the outside and means such as temporary tightening are not required, and the structure around the terminal holder is simplified, whereby the rotary switch itself is made compact. Further, the terminal holder can be surely joined by a simple operation of rotating the terminal holder in opposite directions, and the workability of joining is good. Furthermore, since the same shape product having the hook-shaped projection and the engagement groove of the same shape can be used as both terminal holders, cost reduction and simplification of management can be achieved by sharing the parts.
