Preferably, the front side and the rear side of the boss are correspondingly provided with stop blocks, and the position of each stop block corresponds to that of the third magnetic stripe.

Preferably, the cover plate is circular, and the size of the base is matched with the button cover.

Preferably, a protection ring is vertically arranged on the upper plate surface, and the protection ring is positioned at the periphery of the annular wall.

Preferably, a ring sleeve for sleeving the transmission shaft is arranged in the boss.

Preferably, the transmission shaft is sleeved with a buffer pad, and the buffer pad is located between the boss and the cover plate.

Preferably, the first control board is provided with an LED lamp, and the base and the button cover are made of light-transmitting materials.

According to the knob switch, the first magnetic stripe and the third magnetic stripe are correspondingly attracted, the second magnetic stripe and the fourth magnetic stripe are correspondingly attracted, so that the knob cover is stably sleeved on the boss in a suspension mode, a space gap for pressing down is reserved on the knob cover, when the knob cover is pressed down, the tail end of the transmission shaft touches the tact switch to send out a control instruction, the first Hall switch and the second Hall switch are arranged on the first control panel, different magnetic field changes are generated when the knob cover is rotated by utilizing Hall benefits, different instructions are sent out by Niu Gaizuo in a rotating mode and in a right rotating mode, due to the existence of magnetic force, after a finger leaves the knob cover, the knob cover can recover due to the magnetic force, and therefore functions such as function selection, degree selection and determination of an intelligent closestool can be achieved through actions such as left rotation, right rotation and pressing down. When a user pulls out the button cover, the conducting strip ascends along with the transmission shaft and touches the two first pins, so that the two first pins are conducted, and then signals are transmitted to the first controller through the second control board and the second pins to form a new control instruction. Therefore, when the knob is pulled outwards, functions such as instantaneous cancellation of certain functions of the closestool can be realized, the functions in the existing intelligent closestool have certain time, such as cleaning and drying, and the functions are automatically stopped after certain time, and if a user wants to stop the intelligent closestool independently, the functions can be realized only by pulling the knob cover outwards. The scheme enriches the functions of the rotary switch and simplifies the operation steps.
