Don't drain any at all, just lay down some plastic to protect the wires and
components under the switches
and be ready to replace the old switch with the new one with a quick
manuver of getting the tip into the hole
the threads started.  Don't be afraid to use your finger to stop the flow
if you fumble.   With a bit of practice
and choice swear words you should have no trouble getting the new one in.
Just keep the fluid off of the
wires and such.....
