A safety switch arrangement is provided for an electronic flash for automatically discharging the main storage capacitor in response to the user deliberately or inadvertently removing the cover from the flash housing. The electronic flash is of any ordinary type comprising a DC-to-DC converter with a step-up transformer and the safety switch arrangement is connected to discharge the main storage capacitor through the secondary winding of the DC-to-DC converter transformer thereby eliminating the need for a separate bleeder resistor.
