Abstract
A mounting structure is provided to mount, on the same circuit board, two types of electrical parts in each of which an operating member is rotatably supported by a housing including sliders and a conductive pattern, such as a contact pattern, and which are similar in arrangement of terminals to extend terminal-insertion holes of the circuit board. Each of the electrical parts has a positioning protrusion protruding from its bottom face, and the position of the positioning protrusion differs according to the type of the electrical part. In a mounting region of the circuit board for each electrical part, a positioning hole is provided in which only the positioning protrusion of the corresponding electrical part can be inserted. Preferably, the positioning protrusion protrudes from a bottom face of a bottom plate member attached at the bottom of the housing.
