A current limitation in Power BI SWITCH measures (and all Power Pivot actually) is that a SWITCH measure must have a single format. It is currently not possible to conditionally format the measure result based on any criteria - it is one single format only. There are valid use cases where you may want to change the format of the SWITCH measure depending on the result. Consider the following SWITCH statement myMeasure = SUMX(MeasureTable,switch([selected measure], 1,[Total Sales], 2,[Total Cost], 3,[Total Margin], 4,[Chg Sales vs LY %] )) The first 3 results are all currency format, but the last result is a percentage format. This currently can't be controlled. I would like to see an optional 3rd parameter in the SWITCH statement to set an alternate number format.
