In the relay - contactor control circuit contacts simplification, the specific methods are logical expressions and experiences simplification Simplification Act

In the design of the relay - contactor control circuit frequently encountered when multiple occurrences of the same label contacts phenomenon, and cost savings in order to simplify the circuit design must be simplified for contacts. In the relay - contactor control circuit contacts  Circuit breaker , the specific methods are logical expressions simplification and experience Simplification, the former requires the designer has a good mathematical derivation ability, when the control  air circuit breaker  complex, due to the logical expression too cumbersome and error-prone process of mathematical deduction, is not practical; latter mainly depends on the designer's electrical controls design experience, the results are often not the most simplified simple circuits. Therefore, to find a theory is relatively simple,  mcb circuit breaker  simplification tool for relay - contactor control circuit design is important. I will be commonly used in electronic circuit simplification Karnaugh map used in the relay - contactor control circuit contacts simplification to study the Karnaugh map in the relay - contactor control circuit contacts simplification of the application.
