[0026] In the waterproof display knob 100 provided by the embodiment, the user can rotate the rotary cover 40, and the encoder 201 senses the rotation of the rotary cover 40. The encoder 201 outputs different signals to the circuit board 20 according to the rotation angle of the rotary cover 40. The circuit board 20 controls the display piece 50 on the rotary cover 40 to display the corresponding information picture according to the different signals of the encoder 201. The user can also press the rotary cover 40. When the rotary cover 40 is pressed, the cover shell 30, the encoder 201 and the circuit board 20 are all moved downward at the same time, so that the circuit board 20 can press and touch the contact switch 202, and the contact switch 202 is in contact. Then, the circuit board 20 can control the corresponding operation of the external fitness equipment according to the contact of the contact switch 202. Since the base 10 is movably connected with the cover shell 30, when the user presses the rotary cover 40, the cover shell 30 can be moved downward relative to the base 10 under the extrusion of the rotary cover 40. Since the cover shell 30 covers the circuit board 20 and is fixedly connected with the circuit board 20, when the rotary cover 40 is pressed, the cover shell 30 can move downward with the circuit board 20 to press the contact switch 202, so that the cover shell 30 fixedly connected with the circuit board 20 can effectively cover the circuit board 20 when the circuit board 20 can press the contact switch 202, so that the circuit board 20 cannot be contacted by water.
