Relay 9-9519 B : fitted on which type of aircraft ?

[gilles collaveri]

dear all

Recent diggings in Tarbes airport (South West of France) brought to light a plate of a relay with P/N 9-9519B

I could see here :

https://www.deutscheluftwaffe.de/?s=9-9519

that it was installed on Ju88.

But in Tarbes, we had JG101 with Bf109, FW190, Arado 96 and other Bucker Jungmeister..

So, my question is : on which type of aircraft was the relay 9-9519B fitted ?

Thanks for your expertise;

Gilles

I have found a similar one ending in B1, coming from a Bf110.

Thanks mimithem.
Indeed, I received an answer I share with you (so, it was fitted on many aircraft types)
All best

The Relaiskastern 9-9519 B was a very common part on many WW2 German aircraft with the electrically operated VDM propeller system. As you can see from its "9" equipment group number, it was a very closely related to the engine equipment, it was an aero-engine sub-system. The Relaiskastern functioned to switch the higher operating current to the pitch motor, using the lower current of the propeller control system.
From your list, it was fitted on the Bf 109 E models with Auto propeller control (and all later versions of the Bf 109).
