Embodiment

As shown in Figure 1 and Figure 2, the bottom is provided with static iron core 14 in the housing 1, and housing 1 internal upper part is an active copper 2, active copper is silver point 3 on 2 two ends, fixed copper 4 is connected on the housing 1, and quiet silver point 5 is arranged on the fixed copper 4, the position that this quiet silver point 5 faces below moving silver point 3; Active copper 2 middle-ends are connected with moving iron core 6, and moving iron core 6 hypomeres are provided with stage clip 8 between the static iron core 14 on moving iron core 6 lower ends and the housing 1 in the scope of inhaling iron coil 7; Inventive point is to connect a connecting rod 9 on moving iron core 6, connecting rod 9 other ends are connected with sensitive switch 10, sensitive switch 10 is normally-closed contacts 11, this normally-closed contact 11 is connected with suction iron coil 7, inhaling on the iron coil 7 has signal to export IC circuit 12 to, this IC circuit 12 is connected with hold-in winding 13, and the circuit of normally-closed contact 11, suction iron coil 7 is in parallel with the circuit of IC circuit 12, hold-in winding 13; The bottom of hold-in winding 13 in housing 1, moving iron core 6 lower ends will have been moved iron core 6 and inhale because inhale iron coil 7 in the scope of hold-in winding 13, thus hold-in winding 13 can be arranged on suction iron coil 7 below.Whole device constitutes this contactor 15.

When contactor 15 is not worked, as shown in Figure 1, to inhale iron coil 7 and do not switch on, moving iron core 6 is not inhaled, and moving silver point 3 does not contact with quiet silver point 5, so contactor 15 is not worked;

When contactor 15 work, as shown in Figure 1, 2, inhale iron coil 7 energisings (closing) as K switch, attract moving iron core 6 to get off, overcome the upwards elastic force of stage clip 8, active copper 2 is downward, moving silver point 3 on it contacts with quiet silver point 5 on the fixed copper 4, and circuit is connected, contactor work; Moment after moving silver point 3 and quiet silver point 5 contacts conducting, connecting rod 9 on the moving iron core 6 is downward, make sensitive switch 10 actions that are attached thereto, the normally-closed contact 11 that to connect with suction iron coil 7 disconnects, inhale iron coil 7 no powers, and the signal that suction iron coil 7 no powers are produced is gathered and is exported in the circuit of connecting with hold-in winding 13 by IC circuit 12, make hold-in winding 13 energisings, because the moving iron core 6 that gets off is in the scope of hold-in winding 13, so the power of hold-in winding 13 is as long as very little also still can holding moved the upwards bounce that iron core 6 overcomes stage clip 8, keep motionless, contactor works on.
