There is no module which will help you here.


A quick idea: You might modify a trigger inverter module:
- Connect the base of Q1 with 470k resistor to +12 Volt
- Replace R1 by 10k (perhaps it can remain at 47k)
The 12V on Input create a low on the Inv Out. If the switched trigger 
closes the connection to ground on the input it is like a low on Input 
and the Inv Out will raise to high.

No guarantee at all....
