An energy-saving magnetic lock comprising: a first lock module mounted to a part of a door such as a doorframe; and a second lock module, mounted to the other part of the door such as a door panel which can pivot about the doorframe, for interacting with the first lock module, wherein the first lock module comprises: an electromagnet (1); a slot (12); a trip lever (11) inserted inside the slot; a sensor (13) equipped at the slot end; a member, which is arranged between the trip lever (11) and the slot (12), allowing the trip lever to move toward the slot opening axially a predetermined distance when the pressing force on the head of the lever (11) is less than the predetermined value; a circuit control board (15), wherein the trip lever (11) has a length equal to the distance between the slot opening and a surface of the sensor (13) facing the slot opening, the second lock module comprises: an iron plate (2) installed on or in the part of the door panel by a main screw (21), wherein the main screw (21) comprises: a rod whose end passes through a counterbore (22) of the iron plate (2) and being secured to the part of the door; and a cap (211) abutting against the head of the lever (11) when the electromagnet (1) and the iron plate (2) are sucked together and wherein a first elastic member (23) is arranged between the iron plate (2) and the cap (211) of the main screw (21), and a second elastic member (24) is arranged between the iron plate and the part of the door. The lock can save energy and have added alarm function thereby security is strengthened.
