Claims

[Scope of utility model registration request]

A first switching contact and a second switching contact each having a movable contact that selectively connects and separates from the first fixed contact and the second fixed contact, and the movable contact of each switching contact is connected to the first fixed contact. Providing a relay equipped with an electromagnetic device that swings the movable contact so as to selectively contact either one of the second fixed contact,
A rotation direction switching device for a motor, wherein each movable contact of each switching contact is connected to both ends of a DC motor, and a DC power source is connected between a first fixed contact and a second fixed contact of each switching contact, The electromagnetic device includes a pair of legs disposed substantially parallel to each other, and an iron core with one end of both leg pieces magnetically coupled via a bridging piece;
A first coil and a second coil are respectively wound around each leg piece of the iron core, and are arranged approximately parallel to both leg pieces between the two leg pieces of the iron core, and one end is magnetically coupled to the bridge piece. a yoke, and an armature whose intermediate portion is pivoted to the other end of the yoke and whose both ends are opposed to the other end surface of each leg of the iron core, and whose one end is coupled to the intermediate portion of the armature. At the same time, the movable contacts are provided at the other ends of a pair of movable springs each extending toward each end of the armature, and when both coils are not energized, both movable contacts become the first fixed contacts of each switching contact. Upon contact, the armature is located at an intermediate position in the swing range, and when either one of the coils is selectively energized, one of the movable contacts comes into contact with the second fixed contact as the armature swings. A motor rotation direction switching device characterized by:
