在产ATEX Illuminated Green Push Button 24V
Eaton M22 ATEX-certified illuminated green push button.
常见应用
Start button on ATEX-certified motor starters in refineries and chemical plants. The illuminated LED confirms the circuit is active — critical in noisy environments where audible feedback is insufficient. Zone 2 rating covers most general refinery areas.

ATEX Zone
The hazardous area classification. Zone 1 = gas likely present. Zone 2 = gas unlikely. Zone 21/22 = combustible dust.
|
Zone 2, Zone 22
|
|
Certifications
Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.
|
ATEX, IECEx, CE
|
|
Color
Button/actuator color. Green = start/go, Red = stop/emergency, Yellow = caution, Blue = reset (per IEC 60204-1).
|
Green

Cutout Diameter
The hole size you drill in your panel to mount this button. 22mm is the most common industrial standard worldwide.
|
22.5mm

LED Voltage
The voltage required for the built-in LED. Must match your control circuit voltage (typically 24V DC or 230V AC).
|
24V DC

|
Temperature Class
Maximum surface temperature. T6 (85°C) is most restrictive. T1 (450°C) is least. Must not exceed auto-ignition temp of the gas.

安装快速参考
Panel cutout: 22.5mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

故障排除
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
