Circuit board module

摘要

The module has a printed circuit board, and conducting paths arranged in the printed circuit board. A connecting device e.g. screw, is provided at the printed circuit board for direct mechanical or electrical connection with another printed circuit board module comprising a similar connecting device. A coupling device facilitates coupling of a power supply of the conducting paths for forming an end module. An LED (8) is connected with the conducting paths. An independent claim is also included for an arrangement of a set of interconnected printed circuit boards.
