So you have looked at those switches in person? How much thicker & bigger are we talking? Slighter thicker should not be a real issue cos there should be some leeway. Damn I was planning to get some.

wildlifephotog · 09-03-2009, 09:39 AM

Yes, I have both Z1-p and Z50 switch on my table. They are twice as thick, and twice as big in both length and width.
There is almost zero leeway in size.

I'm trying to get the dimensions of the Canon switch, CH90233000, but no luck yet.
The Pentax switch is 1.5mm thick, and 6mm square.

That's strange. According to my own Z-1p pic above, the switch should be around 7mm wide (judged based on the hot shoe), while the DS switch is 6mm. If doubled in side it would be 12mm wide, which is very big. I had 2 Z-1p spare switches b4 and I don't remember it being that big.

10mm square by my digital calipers. 2.25 thick. Better than eyeballs and a ruler. This is way too big. It will not even line up with the solder points. And the top plate will not go on. I have been trying for a week to find something that works. I'm trying to see if a switch for the 30D or 40D will work.

Looks like the 30D switch is not small either. Do let us know.

My K10D developed the same problem and the estimate was $285.00 to repair it, so I said no thanks. For a little bit more, there are other options out there like the K200D or even the K20D

wildlifephotog · 09-03-2009, 10:47 AM

Right now buying is not an option for me. I will find a way to fix it without Pentax help.
They've made me mad now.

wlachan · 09-03-2009, 11:07 AM

I have this crazy idea. My DS switch once refused to AF when 1/2 pressed near a waterfall. My assumption is that the moisture was too high and somehow affected the unsealed switch. If the switch is in indeed not sealed, perhaps a drop of wd40 might cure it because it is excellent on displacing moisture & removing dirt. Just a drop on top then absorb the liquid from the bottom with tissue paper. I fixed some radio volume controls this way in the past with success. Don't blame me if it kills your camera however.

Well I can report that the tolrences in the camera are tight. A switch only .5 of a mm thicker will not work. It keeps the wiper fingers for on/off from making reliable contact.

You might shave off the bottom side of the silver switch a little in this case (only after you found an appropiate switch 1st of course).

Does anybody have a schematic or drawing that shows how to open up a K10D or any DSLR from Pentax Really? I would like to try and fix my shutter myself.

Just be carefull not to touch any part of the flash circuit or it will be fired for good.

wildlifephotog · 09-03-2009, 11:38 AM

If you are only working on the switch that is no problem.
