Help identifiying rotary switch

[Kang Kel]

After some assistance in identifying this rotary encoder. I believe it to be an Alps rotary encoder but I can't find a replacement model that has a ribbed shaft.


Any ideas????

The knurled shaft option could be ordered in quantity as the original mfr did.
It may not be available through a distributor in small quantities, though.

If you ordered an encoder with a smooth shaft, you may be able to disassemble
both, and transfer the old knurled shaft to the new encoder.

Or you could get the smooth shaft style encoder, and find a different knob.
That's probably easier.

Depends on what's broken. If the encoder guts are bad, but your old shaft is OK, take the new encoder apart, and put the old shaft into it.

the ribbed shaft is not very "alps". could be a chinese knockoff,or may be japanese Noble.

Hello
Please correct me, if I am wrong. I belief all encoders from Alps have got printings on the bottom side. With the printings you can find the model number of the part and start searching for the replacement parts.

"Splined shaft" is the term to use if searching, not ribbed or knurled (knurled is completely different!) Oh, count the splines before ordering!

I don't think it is an alps based on my research now.


The switch came out of an Canary CA906L preamp. Being in Australia they are quoting me $60USD for the part and postage. Trying to see if I can get it myself and was hoping it would be an off the shelf part from Digikey or RS Components.


The preamp has a relay attenuator and the switch controls the volume from the front panel. When turning the switch the volume attenuation actually does the opposite, turn it clockwise turns down the volume. The remote volume control works fine.


Had the switch apart and I can't see anything obvious wrong with it.
