Ok so can we explain why we don't get the switch on surge?
With a resistor dropper the resistance will always be less than the reactance of an equivalent capacitive dropper, that's because the voltage across C is not in phase with the current flowing via C, this means that if the resistor dropper was connected across an AC supply more current would flow compared to the current that would flow if the capacitor in question was connected across the same AC supply.
