In a recent blog post from Cherry GmbH, they recently confirmed that “Cherry MX Yellow” switches available through some online sellers are fake or partially fake.
The fake switches may be using Cherry MX Black housing which explains why the housing itself bears the “Cherry” name and logo, but the original stem has been removed and replaced with a yellow one (and likely the internals as well). Cherry has no idea where these switches came from, but has confirmed that they don’t manufacture yellow stem switches and have no plans to do so in the future. Any official switches manufactured by Cherry can be found on the Cherry website here.
