I wouldn't put any lubricant near it, unless you could mechanically strip it apart, because it's conceivable if you try and externally lubricate it, you'd be getting lubricant dripping inside the camera..
My A77 is fine, which doesn't exactly help, but I've not got the sense it's a widespread or common problem, sounds just like soluable pollutants have seeped into the mechanical interface and dried out, as per sticky keyboard keys etc..

Mine does it too, very annoying, and if I brouhgt it up with Sony I am sure they would say Not a problem. They have alreay told me that the A77 is not water resistant, and that's with all that advertising and writeups and brochures imagine if I complained about a sticky switch?

I have the same problem, i just bought this camera 2 months ago, i'm a such poor guy, i saved so long time to buy it... I'm so sad, damn if Sony don't repair me that i gonna kill myself :-x
Yesterday everything was ok, and now i don't know why this switch don't move like before it's just pain in ass to push it
Anyone have a clue about the origin of this issue ?
Maybe, there are a chance, that it will be recover with time ?:-(

Are you sure there was no sugary drink drop spilled over that switch?
I had the same problem with the (different) switch on my A700. Caused by some party visitor throwing his bear around. A real pain the next day, to free it to a usable level.

Well, this looks like a more than rare issue. Mine is also hard to turn on & off too, but it's variable. Some days, it's not as difficult as others. My plan is to just live with it unless it get to where I can't turn it on & off.
Too bad Sony doesn't have better support for something like this. If they could fix it, it'd probably cost $300

This is not an inherent problem with the camera. It's under warranty so get it fixed.

Miss use of the ability to do 100% pixel peeping is the bane of digital photography because it causes people to fret over inconsequential issues.

I've never had this problem on my A57, but did have it with my on-off on my LX5. Is there enough of a gap between the switch and body to get a length of dental floss (unwaxed) under it (sewing thread should work just as well)? That's what I used to free my sticky LX5 switch. Problem has never repeated.
Mine is like yours, usually sticky, but sometimes worse than others. It does not seem to be weather related, i.e. temperature or humidity. It does not seem to be getting any worse, but it certainly is not the way it should be. The feel is like two pieces of plastic that have been galled with wear rubbing together.Well, this looks like a more than rare issue. Mine is also hard to turn on & off too, but it's variable.

You have to read more carefully. It is claimed to be 'weather sealed', not 'water resistant'. And nobody knows what 'weather sealed' really means... but it offers a clue regarding the stiff power switch. Maybe there's an O-ring or similar barrier under there intended to keep stuff out of the interior of the camera, and maybe that barrier causes additional friction.

Owned my a77 since the first week it came out and have also experienced this issue.
Some days it's sticky,
others not,
still others it I have to really put some thumb effort that makes me fear I'm going to break it & it'll have to go in its first Sony service visit... but hasn't broken yet.
then the issue totally disappears for awhile.
Perhaps, something to do with ambient humidity and/or temperature?
Have learned not to let it get the better of my nerves, they are taut enough.
I still love mine and it's always within reach. I say don't let it bother you until it breaks!
Besides, I'd rather it err on the side of being too stiff rather than too loose and risk turning on inadvertently all the time with my Rstrap as my a700 used to!

Thank you to share your experience, i guess you found out the origin, yesterday night i was in party there are lot of beers of course, i didn't drink, but maybe a friend who i ask to shoot me, have some dirty finger with sugar or anything...
I have try to use alcohol 70° to clean around the switch, first, it looks really powerful, the switch was dynamic like before, but just 1 hour later, the strange sticky moving, come back! u__u
@Dustinash
300$ it's a just damn scam, hum i think about a alternative of warranty or repairing cost : buy a grip, i find one in 200$ it's even expensive but there are another new switch. Hope i can pay in three times...
I'm really affraid to force the main switch cause when i have a lumix Bridge years ago, it was submerge on water and after that, there are exactly same problem : First the switch sticky and 1 day later it slide like in skating rink then it died eventually!
I called Sony assistance, they just tell me to call another Technical Service who can diagnose my issue, and when i call it, they tell me to call the first number again or just send my camera and see what happen...>.< I hate them.
Btw i love this A77.
I had such problem. Dental floss really helped me out. I cleared the switch with floss and found several grains of sand on the floss afterwards.
My advice — start clear carefully from the flange (in front of the switch) between the body and the switch. And use unwaxed dental floss only!

If floss by itself does not work, try dampening it with iso-propyl alcohol. That may cause the foreign matter to transfer to the floss.
I did free an on/off slide switch with a short spray of WD40 on a Minolta film camera, which has been fine ever since, but try everything else first.

Im aware of a great deal of comment, both for and against, about this subject on the internet. In my experience, and that of some colleagues with considerable electronic equipment maintenance experience, that isn't the case. The theory is that the contact surface area is reduced by the silicone deposit, but that increases the current density, which tends to burn off the dirt which is causing the problem. One colleague, with a problem of bad contact on multi-contact switches, actually used silicone grease dissolved in WD40, painted on with a fine brush. It worked very well.
However, I did say try everything else first, and my suggestion of WD40 is because it has a very powerful release action, in cases of mechanical stiction, which this problem seems to be.

The on/off switch on my A77 feels like it has a notch half way between the on and off positions and before I became aware of the problem the switch used to stick sometimes in the half way position even though the camera was 'on'..
Now I know that this can happen I ensure that it moves all the way from off-on-off. I also noticed that skin flakes from one's fingers tend to accumulate in the little 'dished' area around the switch, so I clean it out occasionally with a soft toothbrush - just in case it has something to do with the problem.
