I tend to think it's a speedup switch rather than a memory switch.
It's hard to tell from the third photo, but there could be a second RAM chip soldered on top of the other with the red switch selecting one of the two.
The way to find out would be to enter a short program, set the switch to the other position and see, if it's still there. And vice-versa.
