Abstract (en)
[origin: EP0977233A1] An electromagnetic compensating device and limiting device hold the contact position of fingers (41) to other contact, when the current through a pair of contact (28,30) is less than a limiting threshold, otherwise drive the fingers to retracted position. An actuator drives the ultrafast movement of an opening lock (60) to unlock position, when the resultant force applied to kinematic connecting devices exceeded the preset limiting threshold, otherwise switches the opening lock. An operating mechanism (10) moves to lock and unlock position to release either the loaded or unloaded position of an opening spring (52).
