• a switching mechanism, configured to connect and disconnect at least one movable contact and at least one fixed contact of the electrical switching device;
• a housing element, configured to accommodate the switching mechanism;
• a cover element, configured to cover internal accessory components;
• a test button, movable between an non-actuated position and an actuated position wherein, during the movement of the test button from the non-actuated position into the actuated position, the switching mechanism is configured to disconnect the at least one movable contact from the at least one fixed contact;
• and
• a blocking element, movabley disposed between a first position and a second position and configured such that the blocking element, when the cover element is closed, is held by the cover element in the first position against a pre-tensioning force in a direction of the second position and configured such that the blocking element is embodied, when the cover element is opened, through the movement into the second position, to move the test button from the non-actuated position into the actuated position.
