    • A noise-free low-power consumption wide voltage range DC and AC contactor and remote telephone control system is disclosed. A movable iron core is connected to a linkage. Another end of the linkage is connected to a micro switch. A normal close contact of the micro switch is serially connected to a magnetic coil and is parallel connected to an IC circuit and a retaining coil. A lower end of the movable iron coil is in the extent of the coil so that the magnetic coil attracts the movable iron core to move downwards to conduct the contactor and meanwhile, the magnetic coil will disconnect. The retaining coil is used to replaced the magnetic coil to attract the movable iron core. Since the power consumption of the retaining coil is small and thus the contactor is noise free, lower power consumption, and wide voltage range. Three voltage stages are selectable. The connector can be used with a telephone, a telephone wire, a voice system, a keyboard and a software program so as to be formed as a remote telephone control system with a simple structure, lower cost and be a multi-functional device. Thereby, it can be used widely.

    • An electromagnetic relay is provided with a high current "boost" coil, a lower current normal operating or "seal" coil and a static, electronic circuit that functions under low voltage conditions to energize the boost coil to retain the relay closed. An additional function of this static, electronic circuit is to energize the boost coil for a time interval on initial power application in order to assist in closing the relay, and this time interval automatically varies in the correct direction with variation in the supply voltage available to the coil so that the lower such available voltage is from its normal value, the longer the boosting time interval. At other times, both coils are energized in series at low current to hold the relay closed. This static, electronic circuit is small enough to be integrally incorporated within the housing of a conventional sealed power relay.
    • 电磁继电器具有大电流“升压”线圈,较低电流正常工作或“密封”线圈以及在低电压条件下工作的静态电子电路,以为升压线圈供电以保持继电器闭合。 该静态电子电路的另外的功能是在初始功率施加时对升压线圈施加一段时间间隔,以帮助关闭继电器,并且该时间间隔在正确方向上随着电源电压的变化而自动变化, 线圈使得较低的这种可用电压从其正常值起,升压时间间隔越长。 在其他时间,两个线圈以低电流串联供电,以将继电器闭合。 该静态电子电路足够小以便整合地结合在常规密封电力继电器的壳体内。
