Logic functions within the electrical control circuit

Principle: Logical functions are implemented via connecting the contacts (parallel or in series, for example) within the electrical control unit.

Example: Your order is to build a two-hand control by connecting two buttons together.

- Which logical function you need to implement?
- How do you have to connect the two contacts together to get a two-hand control?

In the following, you will get an overview of the three basic logical functions "AND - OR - NOT" and how to implement them electrically.

Overview about the three basic logical functions:
