<p>The electronics teaching aid box serves for building up of circuits, and for clear arrangement and storage of electric components. It consists of a storage box and an experimental panel. Inserts consists of vertically stacked plastics layers with different moduli of elasticicity, so that the top puncture proof layer is easily movable on the lower more elastic layer and at the same time clamps the inserted components. The inserts are placed horizontally in parallel rows of holes and slots providing a great variety of connections. Metal strips in the slots serve as contact bars.</p> |
