Abstract: In a multifunction hand shower the mode of operation is selected by a change-over mechanism which has a slide (56) which has essentially linear movement. This can be set in three different positions. The slide (56) is connected via a guide and cam mechanism (62, 65) to a first change-over device (37) which can be moved into two different positions. The first position is adopted by the first change-over device (37) in the first mode of operation and the second position in the two other modes of operation. A second change-over device (45) can also be moved backwards and forwards between two positions which correspond to the second and a third mode of operation of the shower. Here, a spring (49) forces the second change-over device (45) into a preferred position. Whether the second change-over device (45) reaches this preferred position depends upon the position of a stop (59, 60) which is attached to the slide (56). The slide (56) is moved for preference by a rocker-type manual actuator (53).
