Abstract：Contactor relays are widely used in the electrical system. Poor-contacting of contactor relays that frequently happens leads to unreliable operation of electrical system. The failure reason of poor-contacting is analyzed in this paper. Two different form contacts of Ag-Cu and Ag-Ni are tested, The effect of contact form is gained from test result. The surfaces of failure samples are studied through the scanning electron microscope (SEM) and X-ray energy spectroscopy (XES). Main reasons of failure are found and the measurement to decrease the poor-contacting of the product is suggested.
