Operating device having a test switch and status indicator

An arrangement comprising an operating device (1) for emergency lighting and a first light-emitting diode (12), a second light-emitting diode (13) and a test switch (11),

• wherein the operating device (1) comprises:
• a first connection (9.1) and a second connection (9.2), and the first light-emitting diode (12) and the second light-emitting diode (13) are connected in parallel between the first connection (9.1) and the second connection (9.2);
• a constant current source (10), and the constant current source (10) is designed to impose a constant current having a first or a second polarity opposite to the first polarity between the first connection (9.1) and the second connection (9.2);
• and
• a control circuit (6) designed to detect a short circuit between the first connection (9.1) and the second connection (9.2) and also designed to control the constant current source (10) so that either the constant current of the first polarity or the constant current of the second polarity is imposed between the first connection (9.1) and the second connection (9.2);
• wherein the constant current source (10) feeds a first current path and a second current path, and, alternatively, the first or the second current path can be connected to the first connection (9.1) and the second connection (9.2);
• and further wherein the first connection (9.1) and the second connection (9.2) are connected via an OR connection of an evaluation circuit, and the evaluation circuit signals an actuation of the test switch (11) if the first connection and the second connection (9.1, 9.2) are short-circuited and are thus at a same potential.
