Abstract

The arrangement is for the projection of digital and analogue circuits appropriate to electronic and computer technology, and utilises daylight projectors. Symbolic representations are included for keys; switches potentiometers and lamps. The assembly consists of a base frame (1) with renewable demonstration plates (2) on either side. The demonstration plates are equipped with electronic circuit components. Circuit leads (10) for the control and display elements (9, 9a) are fed through contacts (12) on the periphery of the demonstration plate. The contact elements (12) correspond with through terminal connectors (14) on the flange of the main frame (1), which has a U-shaped profile in this area. It is tipped by a small rubber extension strip.
