Abstract

A switch arrangement for a lift, preferably a personnel lift or goods lift, including marked pushbuttons and an electrical conductor connection to a control device of the lift. The switch arrangement is provided with at least one elastically deformable plate element with the pushbuttons with the marking on the upper side of the button. A recognition element for the bending in the button is arranged beneath this plate element of the at least one pushbutton. In addition, an electrical conductor connection is provided from the recognition elements to the control device. As a result, it is possible for thinner and more user-friendly switch arrangements to be installed in or outside a lift, in particular for controlling it, or for general functions.
