Patent ID: 6995650

Claim:
An electrical-part mounting structure for mounting electrical parts of different types on a circuit board, wherein each of the electrical parts includes a slider, a conductive pattern on which the slider slides, and an operating member rotatable together with the slider or the conductive pattern, wherein terminals of the electrical parts have similar arrangements and extend through terminal-insertion holes provided in the circuit board, wherein at least one positioning protrusion is provided on a bottom face of each of the electrical parts so that the position of the positioning protrusion differs according to the type of the electrical part, and wherein a positioning hole in which the positioning protrusion is fitted is provided in a mounting region for the electrical part on the circuit board corresponding to the positioning protrusion, wherein each of the electrical parts includes a wafer, and the wafer is provided integrally with the terminals protruding outward, and wherein a structure of the wafer is the same among the electrical parts.
