Question - BRANO switch ID

BRANO switch ID

Hi to All,

I would like to ask your help to ID this switch!

This is a metaldetector find from a WW2 field-airport. The Brano company dated the find from the WW2, or the pre-WW2 era and even the oldest, ex-workers do not remember this piece. Their archive does not contain any info about this switch - they explain it with that there are no product lists from the WW2, or the pre-WW2 era when the factory had foreign owners and during WW2 it was under the German Army's supervisement.

Please let me know what this switch's function was and where had it been used if you know!

Thank you very much!

Nepřijde vám že jde o část té věci co zavírá dveře od místnosti? Klasické "Brano, zavírá samo" ?

Hi bitaxe,

As I could figure it out by the Google Translator you say that it is a kind of door remote operator?

Can you link or send me a picture of it in use?

I think that it is hydraulic closing the door. The company Brano made this for about 100 years.

The way how it could be operated:

Pull and turn the oval shaped button on the right, this way
you can turn the red/white topped lever underneath the edge of it to be fasten. In this position there was a way to use a pin, or plomb-wire to secure it. The switch in the middle is connected to this mechanism, but I did not figure out that yet when was it possible to press it down: if the system is secured or not. I also have no idea about the function of the rotatable third switch yet.

Oh right, bitaxe,

Now I got that what kind of hydraulic door closer mechanism you mean! :]

Something like this:
or no?

Well, honestly I see absolutely no similarity... :[ I'm sure it is something different. Concretely a switch for securing something to be turned on, or off, but this is only my opinion.

But really many thanks for your kind effort!

Yes, it is, but it is the new (i thing from 90´), first model was very diferent. In 70´ Brano made model in my picture, but in 50´made other, and first is other too. I remember minimal 3 model and all is very diferent. Sad
Firm "Brano" is czechoslovak firm for door equipment, and this firm was bought in 30´US firm YALE, in this time Brano start made hydraulic closing door.

Hello Mr. Tintera,

Thanks a lot for this list!

I am researching this find since 2 years now without any result and I have already came across this company history on Brano site.

I was contacting with Brano and as I wrote in my first comment under the picture: even they did not know what this is. :]

Thanks a lot to you as well for your help!

A ja reku, či ma chce niekto identifikovať. Brano zavírá samo (or "Brano self closer", či ako to preložiť !?). Very Happy

Hi again,

I recieved this new letter from Vojensky Historicky Ustav, Praha today and it confirmed my first, security switch impression:

Prague 16 th May 2011

Dear Mr. Havasi,

the images which you sent to us shows the most probably the mechanism of bomb rack lock.
Any way we could not recognise the precise type.

Sincerely yours

Colonel Mgr. Aleš KNÍŽEK
