The practical 4‑pin lead for BOFFIN kits is ideal as a replacement for a lost part or to expand the possibilities of your experiments. Thanks to its robust construction and precise contacts, it ensures a stable connection between modules and a smooth project workflow.

The lead is fully compatible with the popular Boffin sets (75, 100, 300, 500, 750) and expansions Boffin II (AUTO, LIGHT, MOTION, SOUND, GAMES, Green Energy, 3D, My House) as well as Boffin III. Expand your circuits, test new combinations, and build more complex setups without compromise.

• Universal use – fits multiple BOFFIN kit series.
• Easy installation – simple insertion with a secure hold.
• Reliable transmission – clean contacts for stable circuit operation.
• Ideal as a spare part – replaces lost or worn components.
