I found you could check the switches with nothing more than a continuity tester, just make sure that the signal goes from a pin on the module to the switch, then out of the switch to the next switch and so on.

Yes of course you can use a continuity tester but a signal tracer is very useful when checking the switches on these and other similar machines. I worked on a good many of these when at Philips but of course spares were not a problem then. I built a simple signal tracer and found it much quicker than using a testmeter.
