Title: CONTACT MECHANISM AND ELECTROMAGNETIC RELAY USING SAME
Abstract:
Provided is a contact mechanism that has few components and few assembly steps, facilitates size reduction of a device and has a large degree of freedom in design. Accordingly, the contact mechanism comprises: a base 10; a first contact mechanism that causes a movable contact 86a to face a fixed contact 21a, which is provided on one fixed contact terminal 21 out of a pair of fixed contact terminals 21, 22 provided side by side on the base 10, such that the movable contact 86a can come into contact with and move away from the fixed contact 21a; and a second contact mechanism that causes a movable contact 86b to face a fixed contact 22a, which is provided on the other fixed contact terminal 22, such that the movable contact 86b can come into contact with and move away from the fixed contact 22a. In particular, a magnetic field generating means 30, which is equipped with a permanent magnet 31, is disposed between the first contact mechanism and the second contact mechanism such that a reverse-direction magnetic field is generated between the contacts of the first contact mechanism and between the contacts of the second contact mechanism when a reverse-direction current is supplied to the first contact mechanism and the second contact mechanism.
