ABSTRACT OF THE DISCLOSURE A teaching device which can be used to demonstrate electrical circuits and components and their inter-relationship in electrical systems. The device comprises a plurality of plane or rigid panels having flat front and rear surfaces releasably secured in non-overlapping relationship, with front faces oriented in the same direction to a rigid skeletal framework, leaving most of the front and rear panel surfaces operatively exposed. Simulated or actual electrical components with circuit leads extending therefrom are secured to the panels so that they are visible on the front surface. Electrical connectors are secured to and operatively positioned on the front surfaces of the panels. One such connection is electrically connected to each circuit lead of the corresponding component. Wire leads with attachment means at the ends thereof for electrically connecting pairs of electrical connectors are also provided. In a preferred embodiment, portions of each circuit lead are operatively exposed to the rear surface of the corresponding panel and are provided with on/off switches, to enable an instructor, operating on the rear surfaces of the panels to create problems in the circuitry, out of view of a student, who operates on the front surfaces of the panel to locate and solve the problems.
