Working principle: in the initial state, the light rays emitted by the two light emitting elements 3 reach the photosensitive element 4 through the transverse gradient light transmission opening 202-2 of the cross gradient light shielding component 202 and are received by the photosensitive element 4, and the photosensitive element 4 generates a corresponding resistance value. When the rocking bar 2 is forced to swing, the position of the cross gradual change shading component 202 is deviated, so that the light quantity reaching the photosensitive elements 4 through the transverse gradual change light transmission opening 202-2 is changed (more or less), the light received by the two photosensitive elements 4 is also changed, corresponding resistance values are generated (the larger the light quantity is, the smaller the resistance value of the photosensitive resistor is), the photosensitive elements 4 transmit the resistance signals to the singlechip on the PCB 1, and the singlechip identifies the corresponding angle position of the rocking bar 2 according to the resistance values.

Working principle: in the initial state, the light emitted by the two light emitting elements 3 is received by the photosensitive element 4, the photosensitive element 4 generates a corresponding resistance value, and part of the light is blocked by the transverse width gradient light blocking plate 202-3 of the cross gradient light blocking component 202 and cannot reach the photosensitive element 4.
