<P>PROBLEM TO BE SOLVED: To prevent noise and wear on contacts due to armature oscillation in an electromagnetic relay in which movable members are separated from the armature when a fixed contact comes into contact with a movable contact. <P>SOLUTION: A third fixed contact 17c is positioned off a line D passing through two fixed contacts 17a and 17b and a third movable contact is positioned facing to the third fixed contact 17c. When a movable core, etc. is driven toward a fixed core side by electromagnetic force, there are three contact parts, which are the contact part between the first fixed contact 17a and a first movable contact, the contact part between the second fixed contact 17b and a second movable contact, and the contact part between the third fixed contact 17c and the third movable contact, preventing armature oscillation when the three movable contacts hit the three fixed contacts 17a, 17b, and 17c. <P>COPYRIGHT: (C)2012,JPO&INPIT |
