Abstract: A hand shower contains a lamp preferably formed by LEDs that emits light through the jet disk, at least when the hand shower is being used. The power is supplied to the lamp from a battery that is in the handle of the hand shower. In a fixed seat, there is a charger that charges the battery in the hand shower when the hand shower is inserted in the seat. To couple the charger to the battery, there is a coupling device that has one coupling element in the seat and one in the hand shower. The coupling device can function with or without contacts.
