Principle

The first experiment should serve primarily to familiarise the
students with the construction and function of changeover
switches.

Following this, they use two changeover switches for alternate
switching, and so become acquainted with the alternate switching
they daily encounter.

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 do changeover switches and alternate switches work?

Determine how it is possible to switch between two electrical
appliances in a circuit, and how alternate switches are
connected.
