ABSTRACT:
A power saving electromagnetic switch, which is developed to reduce power consumption and implemented using low trouble mechanical parts compared to a conventional electromagnetic switch in which a fixed iron core is electrified to fasten a movable iron core and then a continuous current passes through the fixed iron core during the operation thereof. The power saving electromagnetic switch includes a fixed iron core, a movable iron core and a fastening bar. The fixed iron core includes a guide hole vertically formed from a top thereof, and a through hole formed to penetrate through a side of the fixed iron core and to communicate with the guide hole. The movable iron core moves upward or downward to come into contact with the top of the fixed iron core, and includes a guide rod mounted on a bottom thereof so as to be inserted into the guide hole, the guide rod having a fastening hole formed at an end thereof. The fastening bar is inserted into the fastening hole through the through hole when a bottom of the movable iron core comes into contact with the top of the fixed iron core.
