Abstract

An electrical installation switching device has an insulating material housing; a switching knob protruding beyond the housing on a housing front face and able to pivot between a switched-on and switched-off position about a first pivot axis; a magnetic short circuit current and/or a thermal excess current trigger; a contact site formed from a fixed and a moveable contact piece, a switching lock having a latching site and being triggerable by an excess and/or short circuit current using the trigger when unlatching the latching site; an operator pivotable between a release and an operating position about a second pivot axis, aligned parallel to the first pivot axis, switching knob having an operating contour, the operator and operating contour cooperating by triggering the switching lock using the trigger when the operator pivots about the second pivot axis to hold the knob in an intermediate position between the on and off position.
