Example Embodiment
[0012] in figure 1 Among them, the magnetic core (12), coil (9), circuit board (10), suction plate positioning screw (8), suction plate positioning nut (7), suction plate (4), rubber pad (5) form Has the structural characteristics of a magnetic lock. The most common 270Kg tension in the market, 12V working voltage, and 280mA current of the coil (9) of the magnetic core (12) are used to calculate the inventive features of this embodiment; this embodiment adds a micro-displacement switch ( 2), switch contact piece (1) and spring (6). The magnetic lock main body is installed on the door frame (11), the suction plate (4) is installed on the door leaf (3), and the magnetic lock main body and the suction plate (4) can be relatively matched when the door is closed. When the door leaf (3) is closed, the switch contact piece (1) abuts the micro displacement switch (2) to close the switch.
[0013] in figure 2 When the door leaf (3) is opened, the micro displacement switch (2) is turned o...
