General Electrician, electronics, and electrical drag experimental device

 

The experimental table has more comprehensive safety protection measures and more complete functions. The center of the experimental table is equipped with a universal circuit board, and the circuit board is injected into injection. The surface cloth has porous into a set of connecting jacks. The component box is arbitrarily inserted into the experimental circuit. There are never -fading components symbols, and the lines are clear and beautiful. The box body and the lid adopt a more scientific card structure, which is convenient for m--ntenance and disassembly. The components are placed in the left and right cabinets under the experimental table, which greatly improves the level of management and the degree of planning, which greatly reduces the preparation of teachers' experiment.
