Abstract: An electrical device includes a circuit board (101), a light source (104), and a light guide (105). The light guide receives light from the light source and conducts the received light to an end of the light guide so that the light crosses, in a direction parallel with the circuit board, an edge of the circuit board. The end of the light guide constitutes a display surface for showing the light to a user. On a fringe area extending from the edge of the circuit board a distance (D) towards the opposite edge of the circuit board, the light guide is between geometrical planes parallel and coinciding with surfaces of the circuit board. Hence, the light guide does not require room in directions perpendicular to the circuit board. Therefore, for example, more connectors, key buttons, and/or other instruments can be placed on a control panel of the electrical device.

Abstract: A connecting structure for printed circuit boards has two printed circuit boards. At least one of the two printed circuit boards is a flexible printed circuit board, and each one of the two printed circuit boards has at least one connecting portion. The at least one connecting portion protrudes from an end of the printed circuit board, and is soldered on a top surface of the other printed circuit board. Each of the printed circuit boards is attached to the other printed circuit board only by a part (connecting portion), such that the solders on the connecting portion can extend forward and in two transverse directions beyond the connecting portion, thereby increasing the contact area between the solder and the top surface of the other printed circuit board. Therefore, the connecting structure can firmly connect two printed circuit boards and can enhance the resistance to pull.
