More specifically, the invention states that two ends of the moving shaft are respectively provided with cylindrical shafts of the same diameter. One end is used for switching force transmission, and the other end is used for balancing water pressure. The cylindrical shaft has an interference fit with the connecting sealing ring and the connecting hole. When water passes through the water chamber, the chamber is filled with water, and both sides of the moving shaft are subject to the same pressure. Only when the force areas at both ends are the same, the switching will not be affected by the water pressure. There is a sealing ring at both ends of the moving shaft. The friction between the sealing ring and the moving shaft ensures that the moving shaft can maintain a sinking state when it is paused and will not be impacted by water pressure and return to its original position. A plurality of first bumps with guide slopes are provided in the water-passing cavity. A missing groove is provided between the first bumps. The missing grooves have different sizes due to the support blocks. The missing groove of the support block is connected with the first convex block and is used to support the pause plug in the pause state. When the moving axis is switched, it moves up and down in the slot, pushing the pause plug upward and rotating. When the second bump crosses the highest point of the first bump, the spring behind the pause plug pushes the pause plug to follow the first guide slope to rotate until the second The bump contacts the support block and completes the switch from the open state to the paused state. At this time, the button remains in the current state, and the paused state can be distinguished from the appearance. Continue to press the button and repeat the above action. The difference is that the second bump contacts the missing groove without a support block, and the button returns to the open state, completing the switch from the paused state to the open state. The above is the complete cycle of pause switching. It should be noted that the rotation direction of the pause plug should be consistent with the direction of water inflow into the water chamber, which can be clockwise or counterclockwise. This setting allows the water flow to assist the rotation of the pause plug, making the switch smoother. The main functional parts of the present invention include a moving shaft, a pause plug, a body, and a spring. The number of functional parts is small and the space required for structure implementation is small. The structural advantages are particularly obvious when applied to products with small spaces (such as the structure being applied to shower handles). The product has a small number of functional parts and strong functional stability. The force-bearing area at both ends of the moving shaft can be adjusted according to actual needs to adjust the switching force during use.
