[?] Use a row matrix as an input for Switch function?

Questions
1

Hi Friends, I am trying to use Switch function for a programming problem. Having a large number of condition/value sets coming from a previous calculations, I can not write them manually in “Switch” function, though they are present in a row matrix form. How can import this matrix to switch function so that it can work smoothly ? I have already tried the functions like Grid, Flatten, Sequence etc., nothing seems to work. Will appreciate any suggestion. Attached is the *nb file having a small example of this problem. Thanks

What I have -

Matrix = {Condition_1, Value_1, Condition_2, Value_2, Condition_3, Value_3, … , Condition_30, Value_30}

What i want -

Function ABCD which can be used with switch function as -

Switch[expression, ABCD[Matrix]]

to give similar o/p as -

Switch[expression, Condition_1, Value_1, Condition_2, Value_2, Condition_3, Value_3, … ]

Hi, Switch has Holdrest as attribute.
You could perhaps add the 4 that you used in your matrix in the first column. Then use Sequence so this will be evaluated.

Matrix = {4, 3, Odd, 4, Even};
Switch[ Sequence @@ Matrix]
