Abstract: A module includes a first wiring board, a first integrated circuit component mounted on the first wiring board, a second wiring board overlapping with the first wiring board, a second integrated circuit component mounted on the second wiring board, and a connection member disposed between the first wiring board and the second wiring board and configured to electrically connect the first wiring board and the second wiring board, wherein the second integrated circuit component overlaps with the first wiring board and supplies power to the first integrated circuit component via the connection member.

Abstract: A female terminal has a structure that does not allow molten solder to close a pipe section into which male terminal is inserted. Notched recessed sections (9) are oppositely formed at the lower ends of the side faces (3a and 3a) of a female terminal (1). The female terminal (1) is locked by horizontally opening locking legs (7) protruded from the rear surface of a printed wiring board (11) from an inserting hole (12). In such a state, the rear surface of the board is dipped in molten solder (21). When the board (11), is pulled up from the molten solder (12), the solder (21) closing the pipe section (2) in a bridge-like form is turned to droplets and drops from the recessed section (9), because the wettability of the pipe section (2) with the solder (21) is lowered and the adhesion is weakened due to the recessed sections (9). The remaining molten solder (21) attaches to the peripheral edge of the end of the pipe section (2) other than the recessed sections (9) due to the surface tension and solidifies.

Abstract: A multiple contact switch having at least one elastically deformable contact spring that is deformed by means of projections from a plunger to initiate contact with normally-open electrical contacts within the switch. A normally-closed contact piece within the switch also confronts the normally-open contact. Upon deformation of the elastically deformable spring contact, contacts are made and interrupted by means of contacts affixed to the movable contact springs.

Abstract: A snap switch with a self-cleaning function having a switch body with a fixed contact and a movable contact for performing make-break operations. A knob, mounted on the switch body, operates a contact operation member causing the movable contact to abut the fixed contact when the knob is rotated by a predetermined rotational angle and further causing the movable contact to slide on the fixed contact when the knob is further rotated.
