The notification unit 1000 is electrically connected to the circuit board 900 , and notifies whether a window is opened or closed and a malfunction based on an electrical signal generated from the circuit board 900 .

In one example, the second moving member 700 is in contact with the first contact region 910 in the elastic return position, and the third moving member 800 is in contact with the second contact region 920 in the elastic return position. can be contacted. Conversely, the second moving member 700 is separated from the first contact region 910 when moving, and the third moving member 800 is separated from the second contact region 920 when moving. When the window is closed/opened and the handle is operated, the second and third moving members 700 and 800 move or elastically return, respectively, and contact/separation occurs differently in the first and second contact areas 910 and 920 . Therefore, different electrical signals may be generated from the circuit board in each situation.

Specifically, when the circuit board 900 comes into contact with the first contact area 910 and comes into contact with the second contact area 920 , the notification unit 1000 generates a first electrical signal to notify the normal window opening. can do it First, in the closed state, the second rotating protrusion 420 presses the lower end of the second moving member 8700 so that the second moving member 700 is in contact with and separated from the first contact region 910 of the circuit board. can Here, when the second rotating protrusion 420 rotates by operating the handle, the external force pressing the lower end of the second moving member 700 disappears, and the second moving member 700 elastically returns by the elastic force of the spring to make the first 1 comes into contact with the contact area 910 . And, in the open state of the window, the third moving member 800 comes into contact with the second contact region 920 by elastically returning by releasing the engagement. Accordingly, when the first and second contact regions 910 and 920 make contact at the same time, the circuit board 900 may generate a first electrical signal informing that the window is normally opened.

In another example, when the circuit board 900 is contact-separated in the first contact area 910 and contact-separated in the second contact area 920, the notification unit 1000 informs the normal closing of the window. 2 It can generate an electrical signal. In the closed state, the first moving member 600 descends by pressing the button 500 to press the upper end of the second moving member 700, and the second moving member 700 ) is separated from the first contact area 910 by the first moving member 600 . And, as described above, the third moving member 800 is separated from the second contact region 920 while moving by the engaging coupling of the engaging ball 810 . Accordingly, when the first and second contact regions 910 and 920 are simultaneously separated from each other, the circuit board 900 may generate a second electrical signal informing that the window is normally closed.

On the other hand, the circuit board 900 is contacted in the first contact region 910 and separated in contact with the second contact region 920 , or is contact-separated in the first contact region 910 and separated in the second contact region 920 . When in contact with the , the notification unit may generate a third electrical signal to notify the malfunction. For example, it is normal for contact or contact separation to occur at the same time in the first and second contact areas 910 and 920, but when a window is opened due to forced intrusion from the outside, contact or contact separation may occur in only one of them. .

In another example, the notification unit 1000 may generate different sounds or use lighting of different LED colors to notify whether a window is opened or closed and a malfunction. Accordingly, the notification unit 1000 may include a sound source 1010 for generating different sounds or an LED lamp 1020 exposed on the surface of the body.
