たものである。An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 4 shows a perspective view of the whole, and FIG. 5 shows a perspective view of the yoke (3) and the armature (4). Other configurations are substantially the same as the conventional example. As shown in Fig. 5, a slit (9) is formed in the center of the lateral piece (3b) of the yoke (3) in the same direction as the longitudinal direction of the other piece (4b) of the armature (4) to form a recess. Is provided. That is, the width of this slit (9) is formed wider than the width of the other piece (4b) of the armature (4), and the other piece (4b) of the armature (4) is housed in this slit (9). However, even if the armature (4) is attracted and the other piece (4b) is driven upward, the armature (4) does not project above the upper surface of the lateral piece (3b) of the yoke (3). Further, the contact spring (5) is formed in a substantially Y shape and is provided opposite to the other piece (4b) side of the armature (4), and the end portion of the contact spring (5) is bent downward to be different from the conventional one. Similarly, the movable contact (7) is fixed. (12) is a fixed tack. (10) is a body made of insulating material for arranging the upper member.
1) is a terminal plate fixed to the fixed contact (6), (12) is a coil terminal, and (13) is a common terminal connected to the contact spring (5). Then, the armature (4) is not attracted to the iron core (2).
In the state shown in the figure, the other piece (4b) of the contact terminal (4)
Are arranged so as to sink into the slit (9). When one piece (4a) of the armature (4) is attracted to the iron core (2), the other piece (4b) is driven upward, while the other piece (4b) of the armature (4) is slit (9 ), It does not protrude from the upper surface of the horizontal piece (3b) of the yoke (3). FIG. 7 shows another embodiment of the yoke (3), in which a recessed groove (14) is formed in the center of the lateral piece (3b) of the yoke (3), and the other side of the armature (4) is formed. The piece (4b) is arranged to be stored.
