Hi, I've done a search, both here on the forum, and on Google, and haven't found anything regarding this...

My power switch on my D7000 has become increasingly stiff and difficult to rotate between the On, Off and Illumination positions. It was fine when I first got the camera, about a year ago.

I've never spilled anything on it, nor has it ever been exposed to any excessive dust or dirt or anything like that.

The switch is really stiff and it's impossible to rotate it smoothly, it sticks and if I turn it to the Illumination position, it doesn't rotate back as it should.

I even tried, very carefully, introducing a droplet of silicone based lubricant in between the body and the ring of the switch, but it hasn't really helped.

Any advice?

Thanks in advance.

Vlad.

This is the first case I have heard of that issue. It is possible the switch if broken. Sounds like service is required to replace the switch.

I hope the Silicon lube does not migrate into the switch contacts, or it will likely have to be replaced. A special lube is available for switch and control shafts, produced by Caig Labratories called "MCL" that will lube and deoxidize at the same time. The main causes of stiffing control/switch shafts is lube drying out due to dirt, which introduces corrosion on the shaft or bushing.
Don't use any sort of solvent or else the problem will quickly get worse. Since it under warranty, if you plan to send it in for warranty service, don't add any sort of lube or cleaners or they might disallow warranty claims. They would not know what was put into the camera, since it would still be wet, they would probably assume it was contaminated by a spill of something.
If you wanted to do it yourself to save the costs if they would not cover it, you can order the part and replace it if you are handy with tiny screws. The switch has a flex wiring assembly attached that is not hard to plug into the female connector..no soldering needed., only about an hour disassemble and assembly time.

Stan,

Thanks for your reply. I only introduced a very small droplet (sprayed a toothpick until a droplet formed at the tip, then touched it to the small gap between the ring of the switch and the body, and wiped the excess), so hopefully it won't have done any damage.

I don't know how this would've happened though as I take care of my camera, it lives in a proper camera bag when not used, and when I am using it, I'm treating it with care, and I haven't been taking pictures in any sort of excessively dusty, dirty or moist environments. Also, I don't constantly switch my camera on and off when I'm using it, I pretty much switch it on once, and then off either when the battery needs to be replaced or when I come back home from holiday and want to transfer the pictures to my computer, so the switch hasn't even seen any kind of excessive usage.

I'm not sure I want to void the warranty by attempting to do it myself (even though it sounds like a fun little project), so I'll probably try and go down the warranty route first.

This just sounds like something was slightly amiss in assembly (the placement of the weather sealing gasket?).

I'd send it to Nikon, and not do anything more yourself.
