This thread prompted me to replace my CMP/PWR encoder which has been a
problem for several years. When I ordered the encoder Elecraft
recommended replacing all four. The encoders are only $3.34 each plus
$3.50 for shipping.
I took a few pictures and wrote up what I did at
<http://www.n5na.net/s9y/index.php?/archives/26-Replacing-Elecraft-K3-Push-Button-Encoders.html>.

Olli,
The SHIFT/LO control, etc., are mechanical encoders with a typical rotational
life of 100,000 rotations. The are easily replaceable, and we can send you as
many as you need. I believe the price is quite low. I don't believe is is
possible to clean them, as they are sealed.
In contrast, the VFO A and B encoders are optical, not mechanical, and they are
specified at 10 million rotations. But the cost difference between optical and
mechanical is huge (about 40:1). The mechanical encoders are very small,
fitting in the available space, and are a pragmatic choice for the function
controls.
