<P>PROBLEM TO BE SOLVED: To allow a switch using a roller contact as a movable contact to be stably operated by preventing the occurrence of a slip between a fixed contact and the roller contact. <P>SOLUTION: A roller contact 4 is constituted of a plurality of conductive rollers 400 which are arranged side by side with their central axes directed to an axial direction of a roller support shaft 500 and are supported so as to rotate independently of each other. Therefore, when the roller contact 4 rolls on an electrode surface 2a of a fixed contact 2, the respective rollers 400 constituting the roller contact 4 can rotate at different rotational speeds in accordance with distances from a rotation center of the roller contact. <P>COPYRIGHT: (C)2012,JPO&INPIT |
