A point touch switching mechanism has a ball head component, a water separation unit, a switching unit, and a swinging block. The water separation unit can swing with respect to the ball head. The switching unit comprises a slide base connected to the water separation unit and a water separation disk fixedly connected to the slide base, so that the water separation disk can rotate forward when sliding with respect to the water separation unit, and water separation switching can be implemented when the water separation disk rotates with respect to the water separation unit. The swinging block can be connected to the water separation unit in a sliding manner, and the sliding of the swinging block and of the slide base form a connection, so that the water separation unit can drive the swinging block and drive the slide base to slide with respect to the water separation unit.
