Your logic is reversed : you try if $a equal '=' then not valid match
Use '!=' (not equal) or reverse the statements
Code:
a=in
if [ "$a" != "=" ]
then
    echo "Not a Walid match"
else
    echo "Walid Match"
fi

That could also be written
Code:
a=in
[ "$a" = "=" ] && echo "Valid Match" || echo "Not a Valid match"
