permanent damage.
Looking into the guide hole on the keyboard frame,
there is a tab inside the bottom side wall. Examining the bottom square
stem of a single key top, there is a springy latching tab on one side.
Checking the bottom of a double key top, there are two sides of the
matching stem (besides the patented balancing mechanism) constructed
with the springy latching tab.
When any key top is to be inserted onto the keyboard frame, the
tab on the inside wall of the key top guide hole
must
mate a
corresponding springy latching tab as illustrated above. In this way, the
matching stem of a double key must be either at the bottom when the
double key is “vertically” aligned or at the right of the key coverage area
when the double key is “horizontally” aligned. The location for the key-
definition to be programmed for the double key shall then be the bottom
or the right position accordingly.
