Abstract
The invention relates to a defect indicator for an electronic device, in particular a surge arrester, comprising at least two thermal overcurrent protection devices which respond to different fault or overload states and each have a mechanical actuating device for triggering the fault signalling, wherein the mechanical actuating device is in the form of a bolt or pin which acts on a fault signalling element. According to the invention, the at least two overcurrent protection devices are arranged relative to one another in such a manner that the direction vectors of the bolts or pins intersect in an imaginary extension of the movement path thereof, wherein the particular bolt or pin acts on a respectively provided surface side of a displaceable armature and the armature occupies a variable position in the movement path. The armature also has a further surface side which, in the event of an armature movement, in turn acts on the fault signalling element and displaces the latter, for example, and this further surface side comprises at least one wedge slope for this purpose in order to change the direction of force on account of the movement of one of the bolts or pins.
