<P>PROBLEM TO BE SOLVED: To provide a contact device capable of reliably bringing a movable contact into contact with a fixed contact at three contact points when the movable contact and the fixed contact are made to be in contact with each other at the three contact points. <P>SOLUTION: A contact device 1 includes: plural fixed terminals 37 each having a fixed contact 35; a movable terminal 28 which is provided with movable contacts 31a, 31b and 31c each detachably coming into contact with the fixed contact 35, and which performs a relative movement with respect to the fixed terminal 37; and a pressure spring 33 which presses the movable terminal 28 to cause the fixed contact 35 to contact with the movable contacts 31a, 31b and 31c. The contact device 1 is arranged so that a load center x of the pressure spring 33 is positioned on a line L2 connecting a midpoint M1 of a line L1 connecting so that the distance between the movable contacts 31a, 31b and 31c and any two of areas R1, R2 and R3 coming into contact with the fixed contact 35 is the shortest, and a point P1 where the distance from the midpoint M1 in the other contact area is the shortest. <P>COPYRIGHT: (C)2013,JPO&INPIT |
