Abstract (en)
[origin: EP0565008A1] A residual current device (10) moving and stationery contact elements (25, 23), the moving contact elements (25) being mounted on a contact lever (26) which is accommodated in a contact lever support (27). A sliding plate (16) is mounted on a guide plate (15), which sliding plates (16) is displaced over a projection (20) by a tab (29) on the contact lever support (27), in such a manner that a projection (34) which is located on the sliding plate (16) passes into the movement path of a test button (38) during the switching-off process, in such a manner that the test button can no longer be completely pressed in (depressed) in the switched-off state. In the switched-on state, the test button (38) can be pressed in completely, so that a test button circuit having a moving contact element (56) and a stationery contact element (54) can be closed. The sliding plate has a lug (17) which is located in front of an opening (13) which is located in the region of an opening (13) in the front wall (12) by painting the lug with different paints, it is possible to identify through the opening (13) whether the switch is in the switched-on or switched-off position. <IMAGE>
