The second movable piece 232 is located between the second receiving electrode plate 222 and the second transmitting electrode plate 224 and can swing between the second receiving electrode plate 222 and the second transmitting electrode plate 224.

[0066] In this embodiment, the first movable piece 231 is fixedly connected to one side of the first swing arm 9 along a first direction, and the first movable piece 231 is located between the first receiving electrode plate 221 and the first transmitting electrode plate 223; when the rocker assembly 7 swings in a second direction and drives the first swing arm 9 to rotate in the first direction, the rotation of the first swing arm 9 drives the first movable piece 231 to swing between the first receiving electrode plate 221 and the first transmitting electrode plate 223, so that the sensing value of the sensing capacitor formed between the first receiving electrode plate 221 and the first transmitting electrode plate 223 changes, and then the position detection chip 24 detects the swing position of the rocker assembly 7 in the second direction according to the changed sensing value of the capacitor;

[0067] The second movable piece 232 is fixedly connected to one side of the second swing arm 10 along the second direction, and is located between the second receiving electrode plate 222 and the second transmitting electrode plate 224; when the rocker assembly 7 swings in the first direction and drives the second swing arm 10 to rotate in the second direction, the rotation of the second swing arm 10 drives the second movable piece 232 to swing between the second receiving electrode plate 222 and the second transmitting electrode plate 224, so that the inductive value of the inductive capacitor formed between the second receiving electrode plate 422 and the second transmitting electrode plate 424 changes, and then the position detection chip 24 detects the swing position of the rocker assembly 7 in the first direction according to the changed inductive value of the capacitor.

[0072] By setting the switch 5, when the rocker arm is used, pressing the rocker arm assembly 7 causes the rocker arm assembly 7 to press the switch 5 via the first swing arm 10. The bottom end of the switch 5 presses the switch plate 25, which energizes and activates the built-in connection circuit 21 of the entire base plate 1, so as to detect the swing position of the rocker arm assembly 7 when it is pressed and swung. When the pressure on the rocker arm assembly 7 is released, the rocker arm assembly 7 and the first swing arm 10 return to their original positions. At this time, the switch 5 no longer presses the switch plate 25, and the built-in connection circuit 21 of the base plate 1 is disconnected to reduce power consumption. Here, the range of motion of the switch 5 is very small. In the normal state, the bottom end of the switch 5 rests on the switch plate 25, but its gravity cannot close the switch plate 25. Only by pressing can the switch plate 25 be closed and activated, so as to realize power supply when the rocker arm device is used and power off when not in use, thereby reducing power consumption.
