Each combination of capacitors between points a and b in

Each combination of capacitors between points a and b in Fig is first connected across a 120-V

Question:

Each combination of capacitors between points a and b in Fig is first connected across a 120-V battery, charging the combination to 120 V. These combinations are then connected to make the circuits shown. When the switch S is thrown, a surge of charge for the discharging capacitors flows to trigger the signal device. How much charge flows through the signal device?
