Cyclomatic Compleity IF ELSE vs SWITCH CASE

Many code analysis tools like sonar through errors for switch case if used instead of is else for cyclomatic complexity . Is there a number which should be a threshold of when one should use if else and when one should use switch case ? Say if its a case of 50 , to reduce cyclomatic complexity one should use switch case ? Would be good if you could support your answer with an example ?
