The symbol of a square with an arrow is used in electrical diagrams and schematics to represent a timer. Timers are crucial components in elevator systems as they control the duration of certain operations, such as the delay in starting or stopping motors or ensuring specific actions occur after a determined period.

While relays are represented by different symbols, typically involving connections that illustrate their function—either normally open or normally closed—the square with an arrow clearly denotes a timing function rather than a relay's latching or switching capabilities. Understanding these symbols is essential for interpreting control systems effectively in elevator maintenance and installation.
