Abstract:
     The DC contactor has one step-up DC/DC convertor circuit serially connected with a coil and having some delay function. When the DC contactor is started, the convertor circuit provides the coil with a high voltage enough for the coil to start; and after a certain period of time, the convertor provides rated voltage for maintaining attraction. The novel DC contactor has increased capacity or reduced volume compared with available ones and reduced cost and can meet the requirement for use in some specific fields.
