PURPOSE:To make it possible to perform certain electrical connection by simplifying an apparatus, by collecting the connection part of the positive and negative lead terminals connected to a battery and the positive and negative lead patterns on a printed circuit board in the vicinity of the clamp part of the printed circuit board. CONSTITUTION:A printed circuit board 9 is clamped to a screw pipe along with a battery presser 10 by a screw 11. A plus lead pattern is provided to the printed circuit board at the position corresponding to the top surface of the screw pipe 3 and a minus lead pattern 14 is provided around said pattern 12 and the end part of the minus lead terminal 4 contacted with the minus electrode of a battery 17 is provided in a non-contact state. When the battery 17 is mounted to be clamped in this state by the screw 11 and one end of the minus lead terminal 4 is pushed upwardly to be contacted with the minus lead pattern 14 and the plus lead pattern 13 is also contacted with the top surface 7 of the screw pipe 3 to form a closed circuit. |
