Originally posted by bobore I have a K-5IIs body that has recently been developing a rather sticky on-off switch. I tried a drop of isopropyl alcohol, which promptly made matters worse. I followed that up with a drop of olive oil, and that made it better, but it's still not back to like-new operation.
The camera has been well cared for and has a shutter count of approx 11,225. All other functions work properly. My next move was going to be adding another drop of olive oil, but wanted to run it by folks here first.
Not a good idea!
The oil can penetrate and do damage to the WR sealing!

Manual/Repair/clean On-Off-Switch / Shutter-Release-Button - PentaxForums.com Originally posted by bobore Are there other treatments that have proven successful? The only other one I've read about is running water over the switch, and then letting it dry
I tried that and I protected the camera against any water intrusion but used very warm water (that is how it is recommended)
But it didn't do much.
Originally posted by bobore If the switch seriously worsens, is there any significant reason why you couldn't just leave it in the 'on' position, as the camera will eventually power-off by itself, and then restart by depressing the shutter button half way.
The danger with the oil is now more serious and because it is an ON/OFF Switch + Shutter-Release the oil can reach the contacts.
It can mix with the dirt (Usually from sweat etc. from one's fingers, if worse beer or coke etc.)
So no, letting power switch off autmatically is not critical but that eventually you can't use the shutter-release anymore.
The quicker you open your Pentax and take it on the better!
