Thyssenkrupp Signa4

Signa4 was one of the earlier types of fixtures used by Thyssenkrupp. This video shows the wiring of these fixtures and a detailed look at them. They are just like MAD fixtures since they have DMG bases and connect the same way.

The wiring for these buttons is very easy, and the schematic for the buttons is given on the button base. That said schematic I have also created here.
