The WAGO 221-412 2-conductor COMPACT splicing connector is the small reusable lever connector for clean printer wiring: two side-entry ports, transparent inspection housing, orange operating levers, and WAGO’s verified 0.14–4 mm² / 24–12 AWG conductor range for solid, stranded, and fine-stranded copper.
Why this over a twist connector
- Lever-actuated, no tool required. Strip 11 mm / 0.43 in, lift the lever, insert the conductor, and snap it closed. It is faster to service than a twist cap or one-time crimp when you are debugging a harness.
- Two wires, one potential. Use the 221-412 for simple in-line splices, one-in/one-out extensions, PSU lead joins, enclosure lighting runs, and compact Voron/Klipper wiring drops.
- Transparent body with test access. You can visually confirm insertion depth and probe the connection without taking the junction apart.
- Right-sized 221 family. Need more ports? The 3-conductor WAGO 221-413 and 5-conductor WAGO 221-415 are the same 221-series lever-nut format in sibling layouts.

Use it for
- Voron, V0, Trident, V2, and other Klipper printer wiring where you need a serviceable two-wire junction.
- Low-voltage accessory wiring and properly enclosed mains-side printer wiring installed by someone qualified for the circuit.
- Mixed solid, stranded, or fine-stranded copper wire runs where a reusable clamp is cleaner than a permanent splice.
Gotchas
- Not for aluminum conductors, damaged wire, or loose/open-air mains wiring. Use proper enclosures, strain relief, fusing, and local electrical-code practice.
- This is the 2-conductor 221-412. It is not the 3-port 221-413, the 5-port 221-415, or the larger 6 mm² 221-61x series.
