Time difference pressure distribution output device

The present invention relates to a time difference output device, and more particularly to a time difference pressure distribution output device.

In equipment such as machinery and electronics, it is often necessary to perform control with sequential output. For example, the brake control of the bicycle, the lighting control of the luminaire, the movement control of the robot arm, etc., can cause a time difference between the two output actions by the time difference output device, so that the control has a better performance.

Taking the bicycle brake control as an example, the bicycle braking device of the general bicycle presses the brake handle by the rider to drive the brake device to stop the front and rear wheels of the bicycle.
