Abstract
An elevator call button assembly (20) includes at least one call button (50) having a surface (70) that is touchable by an individual to indicate a desired call in the elevator system. A responder (56) provides a tactile indication that the call has been successfully placed. In one example, the responder (56) comprises a vibrating motor that moves a moveable member (52) once the system controller (68) has successfully received a signal indicating the desired call.
