AN ELECTROMAGNETIC DRIVE UNIT AND AN ELECTROMECHANICAL SWITCHING DEVICE |
摘要 |
<p>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).</p> |
