Can capacitors discharge when the circuit is disconnected
If there are other circuits attached to the +5 volt line then you can usually rely on those being the "discharge" resistor. Or you can reposition the switch (and add a normally closed contact) such that when power is disconnected, it shorts out the +5 volt line to ground but, you still need the diode. - Download [PDF]
