Abstract
An operating panel for an elevator includes a panel plate having an opening, a key switch arrangement and, optionally, a human machine interface attached to the panel plate. The switch arrangement includes a cover arrangement, a hinge and a key switch. The key switch is attached to the cover arrangement and is activated or deactivated by a key for transmitting activation signals to the elevator control upon activation. The cover arrangement is attached to the panel plate via the hinge and is displaced between a first configuration in which the key switch is arranged behind the cover arrangement and a second pivoted configuration in which the key switch is accessible from the front side of the panel plate. Thus, the key switch is protectively stored in the first configuration, providing splash water protection and an attractive visual appearance, and is pivoted to the second configuration when needed.
