Default Durst L1200 - what’s this bit for?

Can anyone say what the white switch arrowed below is meant to do? It seems to have no effect. I wondered if it might have been something to do with a neutral density filter but the CLS450 seems not to have that feature.
Just worried I might be missing out on something. 😀

After doing some searching I think it may be a switch for the lights behind the filter wheels. These seem to be taped over on your image. If they don't switch on and off maybe the bulbs are blown. I found the wiring diagram here https://125px.com/docs/manuals/darkr...s%20Manual.pdf

Have a look at the diagram on page 7 of 35.

Yep, the switch should switch the filter wheel backlights off.

If it's not working, then maybe that explains why the filters look like they're covered up?

It's probably a new trend in analogue photography circles;
"Guess that filter setting!"

Well, that’s that mystery solved. Thanks to everyone. And, yes, I’ve taped over the colour filter wheels because I got fed-up of them shining in my face. I’ll take a look and see if I can fix the switch for a more elegant solution. Mind you, the tape does give the Durst a kind of “gangsta” look - a bit like taping over your Leica rangefinder...

Maybe the switch has failed through over-use.......if someone flipped the switch everytime they opened the paper box, then you can imagine the switch could fail quickly.

If the lights being on is a distraction, then maybe find some way of dimming the brightness of the lamp?

A little off the subject.
I made some light baffles for my Durst M605.
I only noticed the amount of intrusive light given out when I moved the darkroom from the loft to the box bedroom.
Simply made with offcuts of wood, mounting card and felt. Also a handy cable grommet from the junk box that fits over the IN/OUT switch for the B filter.
The slot for the 35-66 light box is blocked out using a piece of card and a magnet holding it in place.
I only put them on when doing colour work.
One day I will get round to putting some black card on the walls around the enlarger.
All made on a rainy afternoon when I couldn't go out to play.

Cheers.

I don't have an enlarger that gives out unwanted light, but just before reading your post Nat, I was just thinking a bit of thick black card and a bit of masking tape to hold it onto the enlarger and to act as a hinge, was my way of doing it. Your way is a bit more elegant though.

Terry, I didn't think I had light leaks until I sited the enlarger in the corner of a white walled room.
The main culprit is the slot that the lever sits in to change from 35 to 66 light box.
Not very noticeable with the safelight on, but in total darkness the light leakage is incredible.
That was easily sorted with a piece of cardboard and a magnet holding it in place.
Cheers all.
