The only confirmed keyboard supplied with the Amiga 1000 was made by Mitsumi, using Mitsumi mount, tactile Mitsumi standard mechanical Type 2 switches. The caps lock switch bears an integrated LED, and the return key uses what appears to be a dummy switch of the same design as the switches found in the Monterey K7S keyboard.[1] The keycap legends are dye sublimated. Both the case and the spacebar are made of ABS.
Cherry G80-0777 bears Amiga keys, but has no other Commodore or Amiga branding, and there is no evidence to suggest that it was ever supplied with an Amiga. If it was, then it appears to be very obscure.
The connector is 4P4C, specific to the Amiga 1000. The pins are 1: +5V, 2: Clock, 3: Data, 4: Ground.[2]
