Abstract:
A device for indicating the state of an electrical switching apparatus includes a movable contact arranged movable between a first and a second position. The device includes at least one protruding contact element arranged on the movable contact, at least one contact pin arranged in the close vicinity to the movable contact such that said contact element abuts the contact pin when the movable contact is in the first position and said contact element is at a distance from the contact pin when the movable contact is in the second position. The contact element and the contact pin form an electrical switch and a detector arrangement configured to detect when said electrical switch is closed and by that detect when the movable contact is in the first position.
