Question for those that actually put together the 787 FC switches and the module into which they are attached.
How does the mounting nut fit over the illuminated part of the knob on the end? It looks too narrow to me. I'm assuming that the switch part with the knob and which might contain the spring is removable so that the lower part of the switch plus wiring is pushed through the panel from the underside and the securing nut and washer is then passed down over the threaded portion and tightened on to the panel. How does the top part of the switch with the illuminated knob then attach to the narrow cylindrical part of the switch poking through from below? Subjects: None |

For reference, here's the datasheet for the family of switches that includes the 787 fuel cutoff switch (4TL837-3D):
