Abstract

The handle of a hand shower accommodates a remote control which is triggered by once-only pressure on a key or another deformable element. The remote control contains a piezoelectric radio switch which is accommodated as a closed-off component in the handle. This switch acts on a receiver which is mounted on a wall connection bend and which is connected to a valve in the wall connection bend. The valve can be switched on and switched off with the aid of the remote control in the handle of the hand shower. In the switched-off state, the shower hose is not under pressure.
