There are a few ways to do this, depending on your comfort level with 
quoting (and quasi-quoting).

1:
%%%%
... = #(list (list 'volta #f) (list 'volta voltaCont))
%%%%

2:
%%%%
... = #(list '(volta #f) (list 'volta voltaCont))
%%%%

3:
%%%%
... = #`((volta #f) (volta ,voltaCont))
%%%%

NOTE: The backtick in the third option begins quasi-quoting, which 
allows you to "unquote" (using the comma) so you can reference the 
defined voltaCont variable.
