3. Functional Descriptions (from your diagram)
-
2-position self-locking (1NO+1NC):
Default state: One side ON, one side OFF. When rotated, the other side turns ON and the original side turns OFF. Stays in the new position.
-
2-position self-locking (2NO):
Default state: Both circuits OFF. When rotated, both circuits turn ON. When rotated back, both turn OFF.
-
3-position self-locking (2NO):
Default state: Both circuits OFF (center position). Rotate left: left circuit ON. Rotate right: right circuit ON. Stays in the new position.
-
Self-reset versions:
The key automatically returns to the default position when released (center position for 3-position, original position for 2-position).
