Research Notes
1. What this is
PBARZAF0000C3A is an APEM pushbutton.
2. Part-number decode
- Series: APEM pushbutton
- Type: pushbutton
3. Compatibility & ordering
APEM makes pushbuttons (incl. anti-vandal and illuminated), tactile switches, toggle switches, joysticks, and indicators for industrial and electronic equipment. Match by type, actuation, illumination, sealing (IP rating), and mounting, then use the APEM datasheet to confirm the exact contact and actuator configuration encoded in the part number.
4. Data-quality note
The APEM product line/type is identified; the detailed configuration is left to the datasheet rather than guessed. Flagged decoded-partial.

इंस्टॉलेशन त्वरित संदर्भ
Panel cutout: 22mm. 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.
आयाम
समस्या निवारण
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.
