Denshi Board
A denshi block mounts on a denshi board, which is usually made of plastic to hold the blocks firmly in place. There are no electrical interconnections under the board, and its purpose is simply for securing the blocks. The blocks mount such that their sides touch to make an electrical connection between the terminals. In addition, there are also metal strips for making electrical connections providing two-way and three-way common tie points.
