Abstract
Disclosed is a micro switch having a high capability of cutting off a direct current. In the micro switch including a stationary contact, a movable contact having a closed position where it contacts the stationary contact or an open position where it is separated from the stationary contact, a movable contact rod for supporting the movable contact, a plunger for pressurizing the movable contact rod upon being pressed, and a leaf spring for supplying a driving force to the movable contact rod to convert a position of the contacts being contacted or separated, a permanent magnet is installed at a position adjacent to the movable contact and the stationary contact, so as to extend an arc generated between the movable contact and the stationary contact upon separating the movable contact from the stationary contact, whereby the arc can be fast extinguished.
