I need switch case command to display two outputs with one input

I want wondering if switch case functions are able to put two different outputs with one input? I have the problem when user enters '2' I want the output to become 697hz,1336hz. Or would i have to set up each individual number to an output?

This is my graph 1,2,3,697hz are in a column 1,4,7,* are in a row

1 2 3 697hz
4 5 6 770hz
7 8 9
* 0 #
1209hz,1336hz,

This is what I tried .

function [lowFrequency, highFrequency]=pushbutton_to_DTMF(string)
Number = input('enter #','s');
switch Number
    case{'1','2','3'};
disp('697')
 case{'1','4','7','*'}
       disp('1209')
end
