Tactile Switches 50mA 12VDC Blue LED Silver, Round, Clear
Research Notes
1. What this is
TL1250F120BQRCLR is an E-Switch TL-series tactile switch.
2. Part-number decode
- Series: E-Switch TL
- Type: tactile switch
3. Compatibility & ordering
E-Switch makes tactile, pushbutton (incl. anti-vandal/illuminated), toggle, slide, and appliance switches for electronics and industrial controls. Match by type, actuation (momentary/maintained), illumination, sealing, and mounting, then use the E-Switch datasheet to confirm the exact contact form and termination encoded in the part number.
4. Data-quality note
The E-Switch series and switch type are decoded from the part number (grounded in the e-switch.com catalog and DigiKey listings). The exact contact form, termination, actuation force, and illumination colour are encoded in the full order code — confirm against the E-Switch datasheet for a precise order (not guessed here).

取付クイックリファレンス
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.

トラブルシューティング
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.
