Abstract
The present invention relates to a low-height small-size high-power AC-DC electromagnetic relay with multiunit contact points, which adopts a button structure. One button structure with one seesaw structure is arranged on the top of a casing, the other end of a button drives a movable spring row of the relay through the forward or backward movement of one end of the button and the conversion of the contact points is realized. Because movable springs of multiunit contact point sets adopt the connection of insulation pieces to form the movable spring row, movable spring lead-out pieces form movable spring lead-out piece rows through the connection of the insulation pieces, solder connection of soft connection wires is avoided through riveting connection, and the cost is reduced. Because the button is fixed on the side surface of the casing, the button adopts the seesaw structure, and a support rotation shaft is designed in the middle of the button. When one end of the button is forward pushed and is locked, the other end drive\s a movable spring set of the relay to move, and the contact points are converted; when one end of the button is pushed backward and is locked, the other end leaves the movable spring set of the relay, the states of the contact points regress, and accordingly, the conversion of the states of the contact points of the relay is realized through the button.
