Well, you could monitor the wire which it switches, with a voltmeter.
Alternatively, "hot wire" the starter, as described in my previous post.
Find a suitable length of stout insulated cable (the sort used for
rear-window heaters) and strip a few mm of insulation from each end.
Turn on the ignition. Hold one end of the cable on the starter solenoid
terminal, and touch the other end on the battery live terminal. If the
engine then cranks and starts, but not when turning the key-switch to
the Start position, it indicates that the starter solenoid isn't getting
fed from the key-switch via whatever intermediate relays may exist. It
doesn't mean that it's definitely the key-switch, but it does mean that
the starter motor is ok.
[Make sure that the car is in Neutral or Park - and don't get your
fingers in the way of any rotating machinery or belts!]
If you eliminate the starter in this way, it's back to tracing the path
from the key-switch to the starter solenoid in order to find where the
discontinuity is. Your User Manual will indicate the function of all the
fuses and - hopefully - the relays, enabling you to identify likely
suspects.
