16-20, the embodiment of the present utility model further provides a remote controller, including a switch 500, a motherboard 600, and a function switching structure as in any of the embodiments of the first aspect; the switch 500 is provided with a movable trigger part 510, and the trigger part 510 is connected with the contact end 320 of the function switching structure; when the contact end 320 is provided with the accommodating groove 321, the trigger part 510 is inserted into the accommodating groove 321 and connected with the elastic reset piece 322; the switch 500 is disposed on the main board 600 and is used to switch the remote control mode of the main board 600.

In one possible implementation, as shown in fig. 21, the switch 500 is connected to the motherboard 600, and the switch 500 is connected to the motherboard 600 by a connector, for example. The main board 600 may be a printed circuit board, and the switch 500 is a toggle switch 500, i.e. the switch 500 includes a trigger portion 510, and the trigger portion 510 may toggle the switch 500 or may press the switch 500. That is, the switch 500 controls the main board 600 to switch four remote control modes, i.e., a first remote control mode in which the trigger portion 510 of the switch 500 is not toggled and the corresponding remote controller is not pressed, a second remote control mode in which the trigger portion 510 of the switch 500 is not toggled and the corresponding remote controller is pressed, a third remote control mode in which the trigger portion 510 of the switch 500 is toggled and the corresponding remote controller is not pressed, and a fourth remote control mode in which the trigger portion 510 of the switch 500 is toggled and the corresponding remote controller is pressed. By way of example, the four remote control modes may be a light control mode, an air conditioning mode, a television mode, a curtain mode, and the like. It can be appreciated that the remote control mode may be correspondingly screen-printed in the area of the key 300 exposed from the first through slot 110, and the screen-printing displaying the remote control mode may be correspondingly adjusted along with the switching action of the user, so as to avoid the confusion of the switching mode and enhance the user experience.

Referring to fig. 18, the trigger portion 510 of the switch 500 is inserted into the receiving groove 321 of the contact terminal 320 and is in contact connection with the elastic restoring member 322. The contact end 320 can drive the trigger portion 510 to move relative to the switch 500 through the side wall of the accommodating groove 321, and referring to fig. 21, a toggle groove is formed on the switch 500 corresponding to the trigger portion 510, so that the remote control mode of the remote controller can be switched through the switch 500. And the trigger portion 510 of the switch 500 is inserted into the accommodating groove 321, and presses the elastic reset element 322, so that the elastic reset element 322 always provides an acting force to the key 300 along the direction from the base 200 to the cover plate 100, and the automatic reset of the key 300 after the switch 500 starts from the contact end 320 is facilitated. An elastic reset piece 322 is arranged in the contact end 320 of the key 300, the key 300 is pressed downwards, and a pressing command of the switch 500 is triggered, so that function switching in the Z direction is realized. As shown in fig. 18, a pressing gap is provided between the trigger portion 510 and the guide bar 323, the pressing stroke is shown as 1mm, the height is adjustable, and the automatic restoration of the key 300 can be realized by the elastic restoring member 322 after the pressing. It should be noted that the elastic reset member 322 is designed to improve the pressing feeling of the key 300.

The function switching structure provided by the embodiment of the utility model can be used for a multi-product controller, 4 modes can be switched by holding a single remote controller by a user, different kinds of intelligent products (such as application scenes of televisions, air conditioners, electric curtains, lamp control systems and the like) can be switched and controlled, the simplicity of operation is realized, the added value of the remote controller product is increased, and the user experience is greatly enhanced.
