Working principle:

1. By external mechanical force transmission elements (by pins, buttons, levers, rollers, etc.) will be used to force action on a reed,
2. Producing reed instantaneous action when the action shifted to the critical point,
3. so moving contact with the fixed contact spring at the end of the action point fast on or off.
4. When the force is removed on the drive components,
5. Action reed produce reverse action force transmission element reverse stroke
6. The action reaches a critical point reed, instantaneous reverse action
