Passengers decide whether a lift is “modern” or “aging” long before the doors move—they decide the moment a button lights under their finger. The DA482 (factory code MTD482A101) is Mitsubishi’s 24 mm square, illuminated micro-switch designed for LEHY-II, LEGY, NEXIEZ and modernisation kits worldwide. Gold-plated contacts, IP54 front plate and 3-million-cycle endurance make it the silent guarantor of a crisp “click” year after year. Nanjing Zhuye Elevator Parts keeps factory-sealed DA482 units in anti-static stock for same-day despatch. Below we explain what the button does, how to install it in 90 seconds, and the replacement cycle that prevents expensive “no response” call-backs.
1. What DA482 / MTD482A101 Really Is
-
24 × 24 mm square lattice snaps into 26 × 26 mm European or 25 × 25 mm Asian cut-outs
-
1.5 mm flush lens with 2.5 mm anti-g vandal bezel—graffiti wipes off with IPA
-
Gold-plated micro-switch, 1 A 250 VAC, 0.1 mm contact gap, 3 million cycles
-
12 VDC warm-white LED, 20 mA, 250 cd m⁻² visible at 6,000 lux lobby lighting
-
IP54 front plate, -25 °C to +70 °C, 95 % RH non-condensing
-
Plug-in 6-way JST connector—swap without touching a screwdriver
If the lens cracks, the LED dies, or tactile force drops below 2 N, passengers immediately doubt the entire lift.
2. Where It Is Used
-
Mitsubishi LEHY-II, LEGY, NEXIEZ passenger elevators
-
Thyssen, Schindler, KONE retrofits using 24 mm square lattice
-
Machine-room-less (MRL) or machine-room (MR) installations
-
New build or modernisation—one part number fits all 24 mm square faceplates
3. Installation – 90-Second Swap
Safety: place lift on inspection, lock main breaker, tag out.
-
Pop old button with plastic spudger; disconnect 6-way JST.
-
Inspect socket latch; if cracked, replace 24 × 24 carrier (Nanjing Zhuye part HZ-24-ABS).
-
Snap DA482 into square hole until two clicks—diagonal pull test >25 N.
-
Plug JST: red +12 V, black 0 V, blue/white NO contact to controller.
-
Power up; LED must light and controller must log call within 50 ms.
No laptop, no parameter, no download—true plug-and-play.
4. Daily Operation – What the Button Actually Does
-
Tactile force 4.0 N ± 0.5 N—perfect for gloved or elderly users
-
1.3 mm pre-travel, 0.9 mm over-travel—no finger fatigue
-
Audible click 48 dB—heard by hard-of-hearing, quiet enough for hotels
-
LED dims to 25 % after 22:00 (energy code) via on-board PWM
5. Replacement Cycle & Preventive Maintenance
-
High-traffic office (>1,500 presses day⁻¹) – inspect quarterly, replace every 24 months
-
Residential tower (400–800 presses day⁻¹) – inspect every 6 months, replace every 4 years
-
Low-rise freight (≤200 presses day⁻¹) – inspect annually, replace every 6 years
Replace immediately if:
-
LED lumen maintenance <70 % (symbol looks grey)
-
Tactile force <2 N (no “click”)
-
Contact resistance >100 mΩ at 1 A
-
Lens cracked or pictogram worn >50 % dot area
-
Yellow LED (end-of-life) stays on after cleaning
6. Extending Life – 3 Pro Tips
-
Keep 12 VDC ±5 %; spikes above 16 V halve LED life
-
Clean with 70 % isopropyl, not ammonia glass spray—prevents crazing
-
In coastal cities add optional silicone boot (IP65) to stop salt fog

Conclusion
The Mitsubishi DA482 / MTD482A101 push button is only 24 mm wide, yet it carries the entire brand image of your elevator. A dead LED or mushy switch tells passengers “this lift is old” long before any door motor fault. Stock a handful of Nanjing Zhuye OEM-grade buttons on every service truck, swap them on schedule, and keep callbacks, complaints and one-star reviews off your dashboard — one quiet, illuminated click at a time.
