Claims

[Scope of utility model registration request]

a U-shaped yoke whose central portion is connected to one end of the core located at the center of the coil; permanent magnets disposed oppositely at both ends of the yoke so as to have opposite polarities; a pair of armatures disposed with a narrow gap at the other end and moved by energizing or de-energizing a coil; one end fixed to the armature and the other end fixed to a side surface of the U-shaped yoke; a pair of armature springs each having a lever shape and a part thereof forming an actuator part; a pair of actuator buttons fixed to the tip of the actuator part; and a pair of armature springs driven by the actuator part. A movable contact spring, a movable contact disposed at the tip of the movable contact spring, and a break side fixed contact and a make side fixed contact disposed opposite to the movable contact, and are formed by the respective contacts. A reversible action bipolar relay characterized in that the combination of the two sets of contacts can be changed by changing the direction of energization to the coils.
