Patent ID: 8860535

Claim:
An electrical switching device, comprising: a switching mechanism, configured to connect and disconnect at least one movable contact from at least one fixed contact of the electrical switching device; a housing element, configured to accommodate internal accessory components; a cover element, configured to cover the internal accessory components; a tripping mechanism, movable between a neutral position and a tripping position; and a test button configured to actuate the tripping mechanism and including a stop contour, the test button including a first contact surface and a second contact surface, the first contact surface being embodied for actuating the tripping mechanism when the test button is actuated manually and the second contact surface being embodied for actuating the tripping mechanism when the cover element is opened, the test button being movable between an OFF position, a non-actuated position and an actuated position, the test button being able to be brought into active contact with the tripping mechanism, wherein the switching mechanism, when the test button is moved from the non-actuated position against the pre-tensioning force of a spring element into the actuated position, separates the at least one movable contact from the at least one fixed contact of the electrical switching device, and wherein when the test button is moved from the non-actuated position into the actuated position, at least one area of the tripping mechanism is slideable along the first contact surface to move the tripping mechanism from the neutral position into the tripping position, wherein the switching mechanism, when the test button is moved by the pre-tensioning force of the spring element from the non-actuated position into the OFF position, separates the at least one movable contact from the at least one fixed contact of the electrical switching device, and wherein, when the test button is moved from the non-actuated position into the OFF position, the at least one area of the tripping mechanism is slideable along on the second contact surface for moving the tripping mechanism from the neutral position into the tripping position, and wherein, in the non-actuated position of the test button, the tripping mechanism is disposed in relation to the switching mechanism such that the electrical switching device is resetable from a TRIP position into a RESET-position and from an OFF position into an ON position.
