If you changed a normally closed switch to be normally open, it would have the reverse effect of what it originally did. For example, if the switch was controlling a light, the light would now be on all the time instead of off. This is because when a switch is normally closed, that means the circuit is complete and current can flow freely.

$begingroup$ Even better, because the switch cannot throw infinitely fast, there will be finite lengths of time during which one contact is arbitrarily close to the other, so the voltage gradient arbitrarily high. Hence, the spark will begin the very moment that they separate, and will simply be stretched out as they are pulled further apart. …

For an uncharged capacitor connected to ground the other pin (the side of the switch) is also at ground potential. At the instant you close the switch the current goes to ground, that''s what it sees. And the current is the same as when you would connect to ground without the capacitor: a short-circuit is a short-circuit.
