A hand held shower with a button switching mechanism for switching spray patterns disclosed in the present invention comprises a body, a button switching mechanism and a cover unit. The button switching mechanism comprises a seat, a disc, a lever, a button, a lower ratchet wheel sleeve and an upper wheel bar. Each time the button pressed, the disc will be rotated to a certain angle so that the outlet hole of the disc will align with the different inlets of seat. The inlets of the seat and the channels with different functions of the cover unit cooperate to switch the spray pattern. The spray pattern can be conveniently and accurately switched by pressing the button with one hand and with little effort.
