及び入力側を保護できる。As shown in FIG. 5, transfer contact 8 is placed on the load side,
When used in a circuit that turns the load ON-OFF with other contacts on the input side, the abnormal voltage that occurs with inductive loads can be released to the ground side through the non-linear resistor 7, protecting the load and input side. .
又第６図に示すように、トランスファ接点を入力側に接
続した場合、入力側からの異常電圧から負荷側を保護す
る。Further, as shown in FIG. 6, when the transfer contact is connected to the input side, the load side is protected from abnormal voltage from the input side.
又第４図に於て端子１２を接点１４若しくは１５に接続

花消去ができる。If the terminal 12 is connected to the contact 14 or 15 in FIG. 4, a circuit as shown in FIG. 7 will be formed, and sparks between the contacts can be extinguished.
即ち、前述のようなことが、従来のようにリレー外部に
於けるサージ吸収器の接続を行うことなしに、端子の接
続を変えるだけで容易に可能であると共に外観的にも小
さい電磁リレーが得られるのである。In other words, the above-mentioned electromagnetic relay can be easily achieved by simply changing the terminal connection without connecting a surge absorber outside the relay as in the conventional case, and is also compact in appearance. You can get it.
