Hello;
The different between both is, that at the end of executing the SQL
in ALTER SYSTEM ARCHIVE LOG CURRENT
the LOG is archived!

but with ALTER SYSTEM SWITCH LOG FILE
the Log is ONLY READY for Archiving !!!
( Archiver will archive it when HE HAS TIME TO DO THIS ); There is no garantee that the log is archived immediatly.


I think ALTER SYSTEM ARCHIVE LOG CURRENT
is very importing for backup-routines
