Not sure I understand the need for the test switch.
If I understand correctly to enter "Test mode" one simply needs to leave
the P lead grounded (off) and apply power, in this case turn on the
master. Of course now the whole ship is powered up but this seems a
fairly small inconvenience considering that timing is a pretty simple
affair.
Am I correct in my understanding here?

If you wire per Z-33 where powered support is available only
from the upper switch position for the purposes of confirming
a P-mag's internal power supply during pre-flight, then you
have no way to power up but ignition inactive (control lead
grounded) without the adding the third maintenance or test
switch switch.
