Working Principle:

External mechanical force transmission elements (such as pins, buttons, levers, rollers, etc.) are used to force actions on the reeds. When the reeds instantaneously move to the critical point, they act accordingly. Thus, at the end of the actuation point, the fixed contact springs are used to quickly open or close. When the force on the driving component is removed, when the actuating reed reaches the critical point of the action, a reverse action force is generated, and the transmission element makes an instant reverse action during the reverse stroke.
