SET FOR STUDYING AN ELECTRONIC CIRCUIT AND PHISICAL EXPERIMENTATION

摘要

PURPOSE: A set for physical experiment and an electronic circuit learning are provided to prevent a poor contact between contact terminals by pushing the contact terminals with the elastic force of a spring. CONSTITUTION: Convex parts(11a,11b,11c,11d) and concave parts(12a,12b,12c,12d) are combined with the other lid on the side of a set lid(10). A conductive contact terminal(30a,30b,30c,30d) is contacted with the contact terminal of the other blocks and is electrically conducted. Concave path units provide the path fitted into the concave part of the lid. A magnet(49) is attached to the bottom of the set body unit.
