Summary:Electrical stop position switch for an electromechanical motor drive, whereby the motor is automatically stopped using a special short circuit brake as soon as the stop position switch is turned off. A return diode (4) is placed between the common switching contact (6) and the open contact (8) when this is connected to the second (10) of two control lines (9, 10). Die Erfindung betrifft einen elektrischen Endlagenabschalter für elektromechanische Motorantriebe, wobei der Motor nach Abschalten des Endlagenabschalters automatisch durch eine spezielle Kurzschlussbremse zum sofortigen Stillstand gebracht wird. Dadurch wird jegliches unerwünschtes Nachlaufen, Auslaufen bzw. Rücklaufen des Motors verhindert. Letzteres kann zu endlosen Schwingvorgängen führen, falls der Antrieb unter starkem mechanischen Gegendruck steht.
