３５．３５°から固定接点３７．３７’に切り換わる。The operation of the electromagnetic relay constructed as described above is similar to conventional relays of this type. That is, when the coil 16 is not energized, the card 20 rotates in the direction of arrow I), and the iron piece 28b or the upright piece 19 of the yoke 7 is rotated by the magnetic force of a permanent magnet (not shown).
The movable contact 33°33 is in contact with the fixed contact 35.35
' is closed. On the other hand, when the coil I6 is energized, the iron piece 28a is attached to the tip magnetic pole surface part (shielding plate LZa side) of the iron core [1].
is repelled and the iron piece 28b is attracted toward the magnetic shielding plate 12b, and the card 20 rotates in the opposite direction to the arrow P about the support shaft 4 as a fulcrum. This switches from the movable contact 33.33 or the fixed contact 35.35° to the fixed contact 37.37'.

ため、共通端子３１のインサート時の搬送や位置決めが
極めて容易である。During insert molding, the common terminal 31 is inserted into the surface of the base l at a position indicated by a dashed line A. In other words, the second protrusion 31b is approximately half embedded in the base. In this way, by forming the second protrusion 31b directly below the first protrusion 31a, the first protrusion 31
It becomes possible to open and close the mold 55 and perform crisp cutting regardless of the presence of a (see FIG. 6). Moreover, since the upper and lower parts of the common terminal 31 are located on the same plane during insert molding, it is extremely easy to transport and position the common terminal 31 when inserting it.
