[0007] In a preferred example, the inner side wall of the sealing cylinder is provided with an internal thread, and the sealing cylinder is threadedly connected to the wiring part, so as to improve the sealing effect between the sealing cylinder and the wiring part.

[0008] In a preferred example, a guide inclined surface is arranged at the edge position of the bottom of the sealing cylinder, so that the sealing cylinder can be smoothly clamped into the assembly hole of the control panel.

[0009] The utility model discloses a further configuration in a preferable example can be: the top of fastening nut is provided with step groove, when fastening nut and the inside surface of control panel abut, the bottom of sealing cylinder can be inserted into step groove.

[0010] The utility model discloses a further configuration in a preferable example can be: the bottom fixed connection of button part has elastic sealing ring, sealing cylinder is located the inside of sealing ring, the bottom of sealing ring is lower than the top side inner wall of limit ring groove, to make sealing ring can be closely with the outside surface of control panel abut.

[0011] The utility model discloses a further configuration in a preferable example can be: the button of button part is evenly provided with a plurality of antiskid bosses.

[0012] Summarized above, the utility model has following beneficial effect:

[0013] The power switch can effectively improve the sealing effect between the button part and the wiring part and the control panel, reduce the risk of water stains penetrating into the machine, and thus ensure normal use of the machine. Since the sealing cylinder can be replaced, the staff can select a suitable sealing cylinder according to the thickness of the control panel and the hole diameter of the assembly hole, thereby improving the use adaptability of the power switch.

[0019] The utility model will be further explained in detail in connection with the drawings.

[0020] Refer to Figure 1 , Figure 2The utility model provides an electric switch, including button part 1, the bottom vertical fixed connection has wiring part 2 of button part 1, and the fastening nut 3 is screwed on wiring part 2.

[0021] Refer to Figure 2 、 Figure 3 The outer side wall of the sealing cylinder 4 is provided with a limiting ring groove 5 along the circumference, and the width of the limiting ring groove 5 is the same as the thickness of the control panel. When the sealing cylinder 4 is clamped into the assembly hole, the control panel can be clamped into the limiting ring groove 5. When the fastening nut 3 is tightened, the top of the sealing cylinder 4 is pressed on the control panel by the button part 1, thereby realizing the sealing between the button part 1 and the control panel.

[0022] When the electric switch needs to be installed, the sealing cylinder 4 is sleeved on the wiring part 2, then the wiring part 2 is inserted through the assembly hole on the control panel, and the control panel is clamped into the limiting ring groove 5. Then, the fastening nut 3 is sleeved on the wiring part 2, and the fastening nut 3 is tightened. At this time, the top of the sealing cylinder 4 is pressed on the upper surface of the control panel by the button part 1, and the bottom of the sealing cylinder 4 is pressed on the lower surface of the control panel by the fastening nut 3, so as to ensure the sealing stability between the electric switch and the control panel, reduce the risk of water seepage into the machine, and ensure the normal use of the machine.

[0023] Refer to Figure 2 、 Figure 3 The inner side wall of the sealing cylinder 4 is provided with an internal thread, and the sealing cylinder 4 is threadedly connected with the wiring part 2, so as to improve the sealing effect between the sealing cylinder 4 and the wiring part 2. At the same time, this design enables the worker to select a suitable sealing cylinder 4 according to the thickness of the control panel and the hole diameter of the assembly hole (ensuring that the width of the limiting ring groove 5 is the same as the thickness of the control panel, and the outer diameter of the sealing cylinder 4 matches the hole diameter of the assembly hole), so as to improve the use adaptability.

[0024] Refer to Figure 2 、 Figure 3 、 Figure 4 The edge position of the bottom of the sealing cylinder 4 is provided with a guide inclined surface 6, so that the sealing cylinder 4 can be smoothly clamped into the assembly hole of the control panel, thereby facilitating the worker to install the electric switch. At the same time, the top of the fastening nut 3 is provided with a stepped groove 9, and when the fastening nut 3 abuts against the inner side surface of the control panel, the bottom of the sealing cylinder 4 can be clamped into the stepped groove 9, so as to improve the sealing effect.
