Tactile Switches SPST OFF(ON) 6MM SMT
Research Notes
1. What this is
CB315FP is an NKK switch — line not recognized.
2. Part-number decode
- Product line: NKK NKK (line not recognized)
- Type: switch
3. Compatibility & ordering
NKK Switches makes high-quality toggle, rocker, pushbutton, tactile, and programmable SmartSwitch products for panel and PCB mounting. Match by type (toggle/rocker/pushbutton/programmable), actuation (momentary vs alternate), illumination, mounting, and the electrical rating, then use the NKK datasheet to confirm the exact contact form and termination encoded in the part number.
4. Data-quality note
The exact NKK product line/configuration could not be confidently decoded from this part number. Kept and documented; flagged needs-verification.

安装快速参考
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.

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.
