Thank you I read that before

But what if I need:

case 1 to 50:

case 52 to 270:

case > 270

It is called "switch" for a reason.

If you want to define ranges then use a conditional "if-else" operator instead of a "switch":

     if( x >=   1 && x <=  50 ) { ... }
else if( x >=  52 && x <= 270 ) { ... }
else if( x >  270             ) { ... }
else                            { ... }
