As shown in fig. 5, illustratively, the first groove wall 3141 and the second groove wall 3142 of the clamping groove 314 are provided with limit ribs 315, and these limit ribs 315 respectively abut against opposite sides of the dial 21.

In some embodiments, as shown in fig. 6, the power switch 2 may include a rocker switch having a rocker 22; the actuating member further includes a pressing member 33, one end of the pressing member 33 is connected to a portion of the switch lever 31 between the fixed end 3111 and the actuating end 3121, and the other end is abutted on the seesaw 22, and the pressing member 33 is configured to slide on the seesaw 22 and actuate the seesaw 22 to tilt with rotation of the switch lever 31.

The rocker 22 of the rocker switch corresponds to a portion of the switch lever 31 located between the fixed end 3111 and the actuation end 3121, and the pressing member 33 is disposed between the rocker 22 and the switch lever 31, wherein one end of the pressing member 33 is connected to a portion of the switch lever 31 located between the fixed end 3111 and the actuation end 3121, and the other end is in contact with the rocker 22, and applies pressure to the rocker 22 sufficient to actuate the tilting of the rocker 22.

The pressing member 33 can rotate synchronously with the switch handle 31 under the drive of the switch handle 31, and along with the rotation of the pressing member 33, one end of the pressing member 33, which is abutted against the rocker 22, can slide on the rocker 22, and the first end and the second end of the rocker 22 are located on the rotation path of the pressing member 33. When the pressing member 33 slides to be in contact with the first end of the rocker 22, the first end of the rocker 22 is pressed down, and the second end of the rocker 22 is tilted, so that the rocker switch is turned on; when the pressing piece 33 slides to the second end of the rocker 22 to abut, the second end of the rocker 22 is pressed down, and the first end of the rocker 22 is tilted, so that the rocker switch is turned off, and the second end is opposite to the first end. Compared with the operation mode of directly pressing the rocker 22, the operation is more labor-saving and the operation difficulty is reduced because the moment arm is longer when the switch handle 31 is actuated in the embodiment.

As shown in fig. 6, the vertical distances between the parts on the rocker 22 and the switch handle 31 are not equal, and the pressing member 33 has elasticity in the direction of the switch handle 31 pointing to the rocker 22, so that the pressing member 33 can always apply stable pressure to the rocker 22 in the sliding process, and further, the rocker 22 can be ensured to tilt alternately along with the sliding of the pressing member 33, so that the on-off state of the rocker switch is switched.

Illustratively, the pressing member 33 may be a spring pin, one end of which is connected to the switch lever 31, and the other end of which is capable of telescoping and abutting on the rocker 22.

In other embodiments of the present utility model, the fixed end 3111 of the switch lever 31 may be directly fixed to the inner wall of the housing 1 and not movable relative to the housing 1.

The actuating assembly 3 further comprises a fixing piece 34, the fixed end 3111 of the switch handle 31 is fixedly connected with the inner wall of the shell 1 through the fixing piece 34, and the actuating end 3121 of the switch handle 31 is suspended; the switch lever 31 is configured to bend and deform and press the button member 23 in response to the actuation end 3121 being externally actuated, wherein the button member 23 can abut against a portion of the switch lever 31 between the fixed end 3111 and the actuation end 3121.

The push-button switch is a switch which uses a push button to push a transmission mechanism, so that a movable contact and a static contact are pressed on or off, and circuit switching is realized. The push button switch has a push button member 23 for receiving a press, taking a self-locking switch as an example, when the push button member 23 is pressed once, the push button member 23 moves a certain distance and is kept at the position (i.e., self-locking), and the self-locking switch is turned on; when the button member 23 is pressed again, the button member 23 rebounds and returns to the position before being pressed last time (i.e., unlocked), and the self-locking switch is turned off.

In the present embodiment, the fixed end 3111 of the switch lever 31 is provided with a second through hole, and the fixing member 34 passes through the second through hole and fastens the switch lever 31 to the housing 1. Since the actuation end 3121 of the switch lever 31 is suspended, the switch lever 31 can be bent and deformed under external actuation when the actuation end 3121 is externally actuated, and since the switch lever 31 itself has a certain elasticity, the switch lever 31 can be restored to a deformed state after the actuation force is removed. As shown in fig. 7, the first opening 11 extends in the width direction of the side wall 12, and the actuation end 3121 of the switch lever 31 is suspended and located within the first opening 11 and moves in the extending direction of the first opening 11. Optionally, the fixing 34 is a fastening screw.

The button member 23 is located on a side of the switch lever 31 remote from the wall to which it is attached, and is disposed close to or in contact with the switch lever 31. When the actuation end 3121 of the switch lever 31 is actuated and is bent, a portion of the switch lever 31 between the fixed end 3111 and the actuation end 3121 applies a pressing force to the button 23 to drive the button to switch on and off. Compared with the operation mode of directly pressing the button piece 23, the operation is more labor-saving and the operation difficulty is reduced because the moment arm is longer when the switch handle 31 is actuated in the embodiment.
