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.
