FAST TRIPPING ELECTRICAL SWITCHING DEVICE

摘要

An electrical switching device (10) which includes a latchable contact carrier (14) carrying one or more electrical contacts (13) that can move between positions wherein an associated electrical circuit (11) is closed and open, an actuating mechanism (15) to selectively drive the contacts (13) between closed and open positions, and a coupling mechanism dependent on the presence of a minimum tripping force on the contacts (13). When the minimum tripping force is not exceeded, the coupling mechanism transfers the positioning force from the actuating mechanism (15) to the contacts (13), and when the minimum tripping force is exceeded, no positioning force from the actuating mechanism (15) is transferred and the contacts (13) are driven to the open position for any orientation of the actuating mechanism (15).
