As shown in FIG. 2, when the relay is turned on in (a), the core 6 attracts the armature 1 by energizing the coil 7 wound around the spool 8. At this time, the movable contact 4 formed at the tip of the movable spring 2 separates from the fixed contact 10A and contacts the fixed contact 10B formed on the fixed terminal 9, so that the protrusion 3 separates from the surface of the armature 1. Next, when the relays of (b) and (c) are turned off and completely turned off, the relay O

As shown in (a) and (b), in this embodiment, as compared with the above-described embodiment, a part of the movable contact spring 2 provided with the movable contact 4 at the tip is symmetrically orthogonal to the axial direction. The difference is that the provided substantially rectangular projection 11 is formed longer than the width of the armature 1, and the other portions are the same. The operation of the movable contact spring 2 is the same as the operation in FIG. 2, and the vibration noise is also reduced.
