Principle

The development of computer engineering and the increasing
digitalisation in the transmitting and processing of information
are accompanied by an increasing use of transistors for switching
functions.

This experiment is designed to demonstrate the basic principles
of how a transistor functions as an electronic switch. We recommend
that the differences between mechanical and electronic switches,
and the benefits of electronic switches, be worked out with the
students. The benefits of electronic switches include the low
control power required, the absence of contacts (which tend to wear
out in time), switching times so rapid that they are in the
nanosecond range, and the small size which enables them to be
fitted into integrated circuits.

Benefits


No additional cable connections between the building blocks needed - clear arragned and quick setup

Contact saftey due to puzzle blocks system

Corrosion-free gold plated contacts

Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside



Tasks

How can a transistor be used as a switch?

Investigate how the two switching conditions of a switch can be
realised with a transistor.
