Star buttons mark special floors in buildings

The star symbol on elevator buttons typically indicates special floors. These floors are often for maintenance, utilities, or emergencies. This feature provides a visual cue to quickly identify these floors in buildings. Elevators adopted symbols, including the star, as buildings grew more complex. This helped efficiently guide users to essential floors, especially in high-rise buildings. The star's simplicity and clarity make it easily recognizable. The symbol's use ensures quick access to vital areas in buildings like hospitals or hotels. It can signify emergency access points or restricted floors needing special authorization, enhancing functionality.
