Are we looking at a "Maintained " fitting ? The 3 core is right , the feed to the key switch first...... other side of key feeds the on/off switch and the (L) in fitting.....3rd wire is the switchwire from on/off sw to (SL) in the fitting.

The idea of that is you need to kill the (SL) and the (L) for testing.

How does that sound ?
