Help identify a switches

I was got those from a 'Xiao Ba Wang'(Clones Nintendo FC but with Keyboard),which made in China of course.
It looks like Alps clone but could not mount to ALPS-Like PCB.
It looks like Tai-Hao Aruz switch,but no branded.
linear feeling no branded.

The top of the switch looks different as well. These are textured, while Aruz are (off the top of my head) smooth. Strange.

I had a keyboard with those.

What does the bottom of it look like? I notice that both the Himake and Tai-Hao branded versions have the same underside moulding as the unbranded version that alps.tw posted, as well as ohaimark's:

The JL version however is clearly different.

As for things like the exact surface texture, or whether the top surface of the spring nub is machined or textured, may simply depend on which mould it came out of.
