Faulty Shake Reduction Switch

Hi, the shake reduction in my K10D stopped working recently, and this was put down to a faulty surface-mounted switch on the A200 circuit block. I was told that the only way to fix this, was to purchase a new A200 PCB costing about 20, but I was wondering if anyone knows if the switch can be bought as a separate component? It's a tiny push-to-make (I assume!) switch measuring about 4mm * 4mm * 1.5mm-picture attached. In addition to the soldered contacts, it has a couple of small plastic locating lugs which protrude through the flexible PCB. Name:  SR Switch 3.jpg

Probably not from Pentax.
If you have a local repair shop, they might be abel to order one.
Sadly Pentax is pretty small and these types of repairs get shipped to one of a few repair centers.
If anything, you can try somewhere like C.R.I.S cameras ( and see if they'll send you the part.
Either way, most likely they would only have the PCB anyway and not even be able to sell a single component. Most places would not waste time soldering such a small component when it is easily replaceable with a fairly low priced PCB.

Still, you can try.

Hi, actually it took less time to unsolder & remove the little switch than it would have done to remove the whole PCB (and less risk of damage)! I've had a quick look at various sites selling SM components, but no luck so far. I'm sure it's just a standard switch probably used in all sorts of cameras, i-pods etc, it's just knowing where to look. I'll probably end up getting the whole PCB in the end...

Try Digikey for the switch.

Check eBay for a cheap broken camera to use for parts if you cannot find the switch you are looking for.

Ok thanks to all for your help, here's what I did to fix this problem: I couldn't match the switch, so I bought the complete new PCB, but unsoldered the little switch from it & soldered it into my old PCB. I thought this was less risky than removing & replacing the entire flexible PCB. My camera's now working perfectly!
