Arri 16S/B buckle switch issues

[George Hill]

The buckle switch in my camera seems to not work. At the end of a roll of film you can hear the film catch on it but then the camera keeps running. I’ve checked the override and it is in the correct position. It’s pretty easy to tell that the roll is done based on the frame counter and the sound the camera makes. But is this a huge issue in case something goes wrong like a film jam? I know it’s also not good to run the camera without film in it. Is it an easy fix or do I have to send it in? I see that du-all sells the switches if that’s what I have to replace

As far as I know, the buckle switch is only there to kill the camera if there's a jam (film gets too tight, loses loop, etc)  There's not supposed to be anything that automatically kills the camera when the film runs out.  You just have to keep an eye on that via the film footage/frame counters and the sound and the turning, or stopping of turning, of the feed spool knob.

I have the user manual in front of me.

There is an override, but the buckle trip is intended to cut the power when the film runs out.

On my 16ST the buckle switch stops the camera when the film runs out. And this works quite reliably.

Exactly, which makes me think mine is just non functional.

I guess my real question is am I risking damaging the camera by running it like this? I can tolerate losing a roll of film

Wow, I've had 4 16ST bodies (long story) and that is not what happened on any of them.  They'd merrily run forever, film or no film.  I guess that must be a feature that is not-working a lot!  Interesting.

OK, crow-eating time.  On my latest camera, which I haven't actually shot any film in yet, it will run just fine with no film in it but if you tap the buckle switch, like I guess the end of a roll of film would, it does indeed shut it off, unlike my previous cameras.  Resets by opening the sprockets (like you naturally do when loading a new roll of film)  Learn something new every day...

Yeah that’s how it’s supposed to work, I’m not brave enough to actuate the switch by hand because the manual says not to! Sounds like this is common problem, I will mention it when I get it serviced next but in the meantime it doesn’t sound like a huge risk
