Switch device with multiple water outputs

Abstract

A switch device with multiple water outputs includes a switch valve, a rotary rod, an engagement ring, a first rotary plate and a second rotary plate. The rotary rod is mounted through an opening of the switch valve. The engagement ring has an inner toothed ring and an outer toothed ring formed on a bottom end of the rotary rod. The first rotary plate and the second rotary plate respectively engage the inner toothed ring and the outer toothed ring, and the both rotary plates have multiple holes. As water entering the holes with different number and deviation angle of the first and second rotary plate selectively communicate with each other, different water outputs can be provided.
