Difference b/w Normar Switch & Switch with TURE()

Koritala The "normal" SWITCH statement takes a value as the first parameter and then each pair of statements after that simply checks if that value equals the first value in the pair of statements and if so returns the second value in the pair of statements. For example:

SWITCH( 
  MAX( 'Table'[Color] ), //first parameter this is the value to check
  "Red", 1, // if the first parameter equals "Red" then return 1
  "Blue", 2 // if the first parameter equals "Blue" then return 2
  3  // otherwise, return 3 if the color is neither red or blue
)

SWITCH TRUE is a more flexible version where each pair of statements after the first parameter (TRUE) you can have a logical test which, if it evaluates to true, returns the corresponding value. For example:

SWITCH(
  TRUE(),
  MAX( 'Table'[Color] ) = "Red" && SUM( 'Table'[Value] ) < 100, 1,
  MAX( 'Table'[Color] ) = "Red" && SUM( 'Table'[Value] ) < 200, 2,
  3
