• Button Cap: A plastic cap featuring an "UP" arrow, "DOWN" arrow, or both.
• Indicator Light: Integrated into the button, traditionally an incandescent bulb or, in newer versions, an LED. It illuminates when a call is registered and extinguishes upon the car's arrival.
• Base & Terminal Block: Provides electrical connections and physical mounting.
• Bezel/Frame: This assembly is typically designed to be installed into a separate frame, often part number A4N96899, to form a complete panel.

• Electrical Type: Low-voltage, low-current dry contact signal.
• Indicator Voltage: Commonly AC 28V (typical for Otis 5100/5200 series). Critical: Actual voltage must be verified against the specific controller's design before replacement.
• Operation Principle: Pressing the button sends a switch signal to the elevator's main controller and illuminates the indicator light to acknowledge the passenger's call.
• Material: High-strength, flame-retardant plastic. Metal button caps may also be used.
