Abstract (en)
Actuator for an installation switching device comprising a main current path, further comprising a point of contact in the main current path, which is formed by at least two contact members, whereby at least one of the contact members is movable and whereby the contact members are configured to be separated in a tripping condition under the influence of a tripping device, characterized in that the actuator comprises a bistable buckling membrane carrying the at least one movable contact piece and being configured to snap back from a first into a second stable position under the influence of the tripping device in a tripping condition, so that the point of contact can thus be opened and permanently kept open in the tripping condition.
