will have to put a voltage across the cables and stick a meter across them at the switch end to see if they still connected.
.

No voltage needed. Use the continuity (Ω) range on your meter.
Test across the ends and you should not see any resistance. Then strip and connect the ends together at the far end and you should see somethinbg around zero Ω.

Lest there be any uncertainty/confusion about what you meant, "not see any resistance" obviously means that the resistance reading one got would be very high (probably 'off-range' or 'O/L').

Yep makes sense - will check with them unconnected then connected, when connected resistance should be minimal.

Yep - and the resistance when unconnected should be approaching 'infinity'.
