The key cap 32 can slide reciprocally along the hollow guiding and limiting piece 31 between the first position and the second position, and when the key cap 32 slides along the hollow guiding and limiting piece 31 to the first position, the pressing part 33 presses the tact switch 40 so that the tact switch 40 outputs a confirmation signal for confirming the control and regulation signal; when the key cap 32 slides along the hollow guide stopper 31 to the second position, the pressing portion 33 does not press the tact switch 40. The state in which the pressing portion 33 does not press the tact switch 40 includes two states in which the pressing portion 33 only contacts or disengages the tact switch 40.

In this embodiment, a character is generally provided on the surface of the key cap 32, and the character expresses an instruction to be executed by rotating the hollow knob 40, for example, the character may be "gain", in other words, a "gain" signal may be output by the rotation of the hollow rotating portion 12 relative to the hollow fixed portion 11 during the rotation of the hollow knob 40. The hollow fixing portion 11 is kept motionless, the hollow guiding and limiting member 31 is fixed on the hollow fixing portion 11, and the key cap 32 can only slide reciprocally between the first position and the second position along the hollow guiding and limiting member 31 and cannot rotate around the hollow guiding and limiting member 31, so that when the hollow knob 40 rotates, the key cap 32 does not rotate along with the hollow knob 40, and therefore, characters on the surface of the key cap 32 cannot change positions, and the key cap is convenient for operators to observe, and further convenient to operate.

The hollow encoder 10 may output the adjustment signal based on a change in a signal such as an electric field or a magnetic field, and the hollow rotation portion 12 may output the magnetic signal, the hollow fixing portion 11 may output the electric field signal, and the hollow rotation portion 12 may output the changed magnetic field signal when rotated with respect to the hollow fixing portion 11, thereby outputting the adjustment signal. The specific working principle of the hollow encoder 10 can be combined with the prior art, and will not be described in detail herein.
