The Robotron K7673 is a keyboard produced by VEB Kombinat Robotron in Auerbach, in the then still existing GDR (East Germany). The layout is non-standard. It was designed for at least the Robotron CM1910 computers and uses a custom connector.
As a coincidence, the town where the Robotron keyboards were produced is Auerbach in Saxony, while the western German manufacturer Cherry has its production site in Auerbach, Oberpfalz.
How to disassemble
Loosen all screws at the backside of the keyboard. Then open one clip after the other, and the keyboard pops open.

A time stamp saying that this keyboard was manufactured on Monday, September 25, 1989, only 45 days before the fall of the wall. Little more than a year later, the GDR was history. This explains why this keyboard is unused.

The switch
Typing feeling is not bad. It is kind of linear with a little tactility towards the end of the key travel. Given it is a membrane keyboard, actuation might be at the end as well; however, pulling a keycap and disassembling the switch reveals that the technology is more complicated than the typing feeling suggests.
Keycap, 2 springs and a slider removed.
The slider consists of 2 pieces (that black and white plastic part on the Video key).
Slider and small spring assembled into the switch.
The big spring is attached in the same fashion as 1980s Key Tronic keyboards (see Columbia Data Products).
