抄録(英) The purpose of this work is to compare the operation characteristics using two types of contact with different forms. One has the curved surface electrode that is generally used, the other is notched in the center of the electrode. The advantage of the latter contact may be to make contact force increase. Therefore we can expect to downsize the solenoid coil. Then we investigated the contact resistance, the material wear, and the arc duration. In addition, contact surface was observed by optical microscope to inspect the state of erosion and transfer. According to our research, the contact resistances of both types keep low and stable. The material wear of notched contact is influenced by the made of switching. From the photographs of surface, the behavior of erosion and transfer in two types of contact are different.
