Elevator Button A4N58981 – The Touch That Travels Millions of Floors | Nanjing Zhuye Elevator Parts
Every passenger journey starts with a press. The A4N58981 touch-button combines a vandal-resistant stainless face, capacitive sense element and RGB halo in one 30 mm module, giving instant visual feedback while surviving coffee spills, key scratches and 10 million activations. When the halo stays dark or the lift fails to answer, users blame the entire building. Nanjing Zhuye Elevator Parts keeps genuine A4N58981 buttons in original anti-static trays, ready for same-day despatch so your car calls never stay silent.

Where it works
-

-
Modernisation packages replacing mechanical push-buttons or damaged halos
-
Any controller supplying 24 VDC ±10 % and accepting dry-contact input
Installation method – 2-minute swap
-
Place lift on inspection mode; switch OFF COP breaker.
-
Remove face-plate with plastic pry tool; photograph wire colours.
-
Pull old button forward; release cage-clamp wires.
-
Insert new A4N58981; connect 24 V to pins 1 (+) and 2 (−), halo common to pin 3, NO contact to pin 4.
-
Restore power; halo should light white for 1 s then turn off.
-
Press surface; controller input LED must illuminate and halo change to blue (customisable).
-
Re-install face-plate; torque screws 0.8 Nm to avoid bezel distortion.
-
Log serial number and date in maintenance book.
Replacement cycle & wear indicators
Although contact-less, buttons still age mechanically and electrically. EN 81-70 and site logs suggest:
-
Visual check every 6 months: look for halo dark spots, bezel scratches, cable oil swelling.
-
Function test every 12 months: measure contact resistance < 50 mΩ; replace if > 100 mΩ.
-
Replace entire button every 6 years or 1 million cycles (≈ 400 starts/day).
-
Immediate replacement if:
– halo dead or flickers despite 24 V present,
– no input signal when pressed (capacitive sensor failed),
– bezel cracked exposing live parts,
– ESD damage after lightning (halo locks red).
Pro tip: 60 % of premature failures are traced to over-torqued face-plates—cracks allow moisture into the sensor.
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Clean only with iso-propyl alcohol; abrasive cleaners remove nano-coating and invite fingerprints.
-
Never hot-swap with power on; transients can weld the gold contacts.
-
Keep spare A4N58981 in every service tool bag; at 18 g it costs less than one callback.
-
After heavy cleaning, check 24 V ripple < 1 V; high ripple dims the halo prematurely.
-
Order the “Button Pack” (button + gasket + crimp terminals) from Nanjing Zhuye Elevator Parts to eliminate on-site splicing.
