An electrical switching device includes a switching mechanism, a housing element, a cover element and a test button, which is movable between a non-actuated position and an actuated position. When the test button is moved from the non-actuated position into the actuated position, the switching mechanism disconnects at least one moveable contact from at least one fixed contact of the switching mechanism. Further, a blocking element is movable between a first position and a second position, so 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 the direction of the second position. Further, when the cover element is opened, the blocking element moves the test button from the non-actuated position into the actuated position.
