摘要
Box for installation of didactic diagrams, characterized by being formed by a multi-perforated upper lid box and hollow bottom on whose upper face rests a support pad of a series of springs coinciding with the perforations, capable of receiving, on said perforated upper face, a sheet with an engraved electrical diagram, of which perforations coincide with some of the upper face of the box and with the corresponding ones of a hinged cover on said box, provided with the same number of perforations and equally arranged as the upper face of the box. This; the assembly is equipped with its own power supply or connected to an external one, capable of transmitting its energy to the springs that pass through the upper face assembly of the box, sheet and hinged cover, on which the appropriate connections will be made.
