Mechanism for preventing simultaneous locking of multi-column switches |
摘要 |
Simultaneous actuation of switches belonging to separate columns in a switch matrix is prevented by means of opposed preventing members which slide strokes of predetermined length in opposed directions. The preventing members having competing sections formed on opposite sides of a gap which is less than twice the length of the predetermined stroke and these sections compete for space in the gap when their respective preventing members slide so that only one preventing member can slide the full length of its stroke at a time.
