The 863233H03 is the iconic square illuminated push-button that lights up every KONE MonoSpace® and MiniSpace® landing and car operating panel worldwide. Only 28 mm × 28 mm, this vandal-resistant module combines a stainless-steel faceplate, diode-protected halo LED and gold-plated contacts rated for 5 Vdc, 10 mA logic circuits. A cracked lens or faded halo will throw a “314” fault and leave passengers in the dark. Nanjing Zhuye Elevator Parts keeps thousands of factory-tested square buttons in Rotterdam and Nanjing so you can restore perfect indication the same day. Below is an 800-word field manual that explains correct usage, on-site replacement and the lifecycle that keeps your elevators bright, safe and code-compliant.

2. Tools to carry
-
Square button 863233H03 (Nanjing Zhuye part #KN-BTN-863233H03-SQ) in blister pack
-
2 mm & 3 mm flat screwdrivers, TX10 Torx
-
KONE E-Link Service Tool (EEST) laptop (optional for LED test)
-
IPA wipes and lint-free cloth
-

3. Installation – 2 minutes per button
Safety: place the car on inspection, open the controller disconnect and verify 0 V on the 24 Vdc rail.
-
Photograph the old button wiring – note anode, cathode and switch pins.
-
Depress the bezel latches; slide the module out of the square bezel.
-
Clean the bezel with IPA; remove any glue residue.
-
Connect new 863233H03: LED wires first, then micro-switch.
-
Slide module into bezel until latch clicks.
-
Apply power – halo illuminates steady; press button – call registers and halo extinguishes after door close.
-
Record serial number and date in CMMS.
4. Functional test – prove it to the inspector
a) Actuation force: 1.5 N ±0.3 N at plunger centre.
b) Halo brightness: 120 cd/m² measured with lux meter.
c) Contact resistance: <0.1 Ω at 10 mA test current.
d) LED current: 18 mA ±2 mA at 24 Vdc.
e) Export button map and attach PDF to site file.
b) Halo brightness: 120 cd/m² measured with lux meter.
c) Contact resistance: <0.1 Ω at 10 mA test current.
d) LED current: 18 mA ±2 mA at 24 Vdc.
e) Export button map and attach PDF to site file.
5. Preventive maintenance schedule
-
Monthly – visual sweep for cracked lenses or dark halos.
-
Quarterly – measure actuation force and clean faceplate with IPA.
-
Annually – check contact resistance; replace if >0.5 Ω.
-
Every two years – replace the anti-scratch lens film – keeps display crystal-clear.
6. Replacement cycle – traffic and vandalism decide
KONE specification: 1 million cycles ≈ 10 years at 400 starts/day. Nanjing Zhuye analytics refine this:
-
Light duty (<150 starts/day, clean office): 12 years
-
Standard duty (150–400 starts, residential): 10 years
-
Heavy duty (>400 starts, hospital, mall): 8 years
-
High vandalism (school, station): 5 years – lens and faceplate crack under impact.
Replace immediately if:
-
Halo brightness <50 % – LED chain degradation
-
Contact bounce >5 ms – micro-switch spring fatigue
-
Lens cracked >2 mm – safety and aesthetics
-
Contact resistance >0.5 Ω – arcing pits
