Panel lights out mystery

[ikaros61]

I went flying last night doing touch and goes in ny 1979 Piper Arrow and suddenly all the panels lights went out with the exemption of one. All ther radios were good but the engine and flying instruments were out. The first thing was to check the fuse which turn out to be okay but all were out except one. The racker switch worked, it turn on and off and timmed the one instrument light that was working but the rest were out.

Any ideas were to start?
