PURPOSE: To mount an electrical product to both a printed circuit board with holes and that without holes by providing two sets of contacts and connecting the contacts electrically and mutually for each group of two contacts that belong to each set. CONSTITUTION: A casing 2 of an electric motor 1 has two main surfaces 3 and 4 and two sets of contacts 6 and 7. A pair of contacts 6 are located on the casing surface 3, and these contacts 6 are constituted of a metal strip that can be deformed elastically. A film 8 supports a conductor spot 9 that is provided so that it matches a printed circuit on one surface, especially the contacts 6. The contacts 7 pass through a printed circuit board 14, are inserted through a through hole 15 that is open at the center of a conductor spot 16 that belongs to a printed circuit on the plane in the surface at an opposite side, and is fixed by welding 17. In this manner, an electrical product can be mounted to a plate with a printed circuit by two methods. |
