Switch and List: How to combine?

How do I use a list within Switch?

Switch[expr,form1,val1,form2,val2,...] evaluates expr, matches it to form i,
and returns val i, if there's a match, Null otherwise.  When I put in a list
{form1,val1,form2,val2,...} Mathematica treats it as a single object, and
for the life of me I can't strip off the curly brackets.  The closest I came
was with Sequence, which replaced the curly brackets with parentheses.
