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