电磁驱动单元和机电开关装置
摘要：
本发明提供一种机电开关装置(250)，特别是一种接触器或包括接触器的多功能装置，所述机电开关装置包括至少一个固定接触零件(6)、至少一个可往复于所述至少一个固定接触零件(6)之间而移动以用于断开或闭合电流路径(5a、5b)的可移动接触零件(21)，以及包括轭(210)和线圈(11)及可移动衔铁(215)的电磁驱动单元(201)，其中所述电磁驱动单元(201)适于响应于施加到所述线圈(11)的电压而移位所述可移动接触零件(21)。所述至少一个可移动接触零件(21)和所述至少一个固定接触零件(6)适于在激活所述电磁驱动单元(201)之后限制所述衔铁(215)的移动。
摘要（英）：

An electromechanical switching device (250), especially a contactor or a multifunctional device comprising a contactor, comprises at least one stationary contact piece (6), at least one movable contact piece (21) movable to and from said at least one stationary contact piece (6) for opening or closing a current path (5a, 5b), and an electromagnetic drive unit (201) comprising a yoke (210) and a coil (11) and a movable armature (215), wherein the electromagnetic drive unit (201) is adapted to displace said movable contact piece (21) in response to a voltage applied to the coil (11). The at least one movable contact piece (21) and said at least one stationary contact piece (6) are adapted to limit movement of the armature (215) after activation of the electromagnetic drive unit (201).
