Snap-Clip Stud Button Discs for Paper Circuits (B2B Classroom-Ready)
These are snap-clip stud button discs: a circular felt/fiber disc with a metal clip riveted to a metal stud base. The assembly works as a fastener and a low-voltage electrical contact. Slide a coin-cell battery (CR2032) under the clip and you get a quick, reliable battery holder and on/off switch for paper- and textile-based circuits—perfect for kits, workshops, and private-label STEM products.
Included & Compatible Accessories
- Snap-clip stud button discs (Ø ~25–35 mm, mixed colors)
- CR2032 coin cell (3 V) or CR2016 (optional)
- LEDs (3 mm/5 mm), pre-wired or bare legs
- Copper tape / conductive tape or conductive thread (for e-textiles)
- Craft bases: cardstock, felt patches, foam stickers, safety pins or magnets for badges
- Optional: resistors (for multiple LEDs), alligator leads for demos, printable instruction cards, bag/box packaging with your private label
Keywords intentionally used for search and clarity: stud, snap button, fastener, clip, coin cell, battery holder, felt disc, paper circuit, conductive tape, LED, switch.
How the Snap-Clip Works (Principle)
- The coin cell has polarity: the large flat top is +.
- The metal clip touches the top of the battery (+).
- The metal stud base (back plate) touches the bottom of the battery (–).
- When an LED’s anode (+) is routed to the clip and its cathode (–) to the base (via copper tape/thread), the circuit closes and the LED lights.
- Lift the clip or break the tape path to open the circuit (it acts like a simple switch).
Students directly see: open vs. closed circuits, polarity, contact resistance, series/parallel effects, and mechanical-to-electrical integration using a familiar button/fastener form.
Core Classroom Experiment (10–15 minutes)
Goal: Build a light-up paper badge using one snap-clip stud button disc.
Materials: 1 disc, 1 CR2032, 1 LED, copper tape, card, tape/glue.
Steps
- Mount the disc. Stick the felt disc to the card. Mark “+” near the clip and “–” near the rim/back.
- Lay traces. Run copper tape from the clip area to where the LED’s longer leg (anode) will sit. Run a second tape path from the disc’s rim/back to the LED’s shorter leg (cathode).
- Place the LED. Secure each leg to its tape with a small fold-over of tape.
- Insert the coin cell. Slide the coin cell under the clip with the + side up.
- Test the switch. Press the clip down: the LED turns on. Lift or fold a break in the tape: off.
- Finish. Add artwork or a safety pin/magnet to wear it.
What students observe & learn
- Polarity matters: flip the LED and it won’t light.
- Switching: the clip and paper fold act as mechanical switches.
- Path length/resistance: longer or wrinkled copper tape slightly dims LEDs.
- Parallel vs. series: two LEDs in parallel share current (may dim); series may not light on 3 V, introducing forward-voltage concepts.
Extended Investigations (15–30 minutes)
- Brightness & contact pressure: measure current while gently pressing the clip; discuss contact resistance.
- Wearable circuits: replace copper tape with conductive thread on felt; compare flexibility and durability.
- Thematic builds: constellations, safety reflectors, “light-up emoji,” traffic-light logic with two discs acting as switches.
- Material science: test different tapes/foils; which is most conductive and tear-resistant?
Where These Discs Shine (Application Scenarios)
- Gifts & retail toys: light-up badges, greeting cards, festival pins—simple pull-tab “switch” feels like a snap button moment.
- Education & training centers: low-prep STEM stations; each student gets a self-contained fastener-battery holder that reduces wiring errors.
- Theme teaching activities: Electricity & Magnetism, Wearables, Night-Sky, Safety Signals, Museum-Map Guides (LED lights mark exhibits).
- Science museums / museum-store gifts: 15-minute “make-and-take” kits; branded private label packs aligned with exhibit topics.
- Therapeutic / senior programs: large tactile button-style action; safe 3 V circuits support fine-motor practice and creative success.
Packaging & B2B Customization (for educators, brands, and wholesalers)
Because these are designed for wholesale and program use, you can tailor them to the needs of your customers—teachers, parents, learners—without changing the underlying principle:
- Sizes & colors: different disc diameters, color-coded sets for classroom stations.
- Accessories by audience: pre-soldered LEDs for younger learners; separate components for advanced groups.
- Branding: private label artwork, logo cards, QR video links; kit packaging in polybags, tuck boxes, or retail blisters.
- Market compliance: multi-language instructions, barcodes, and local safety/label norms for your sales region.
- Lesson bundling: topic packs (e.g., “Constellation Card,” “Road-Safety Light,” “Festival Pin”) using the same stud/snap-clip platform.
Safety & Good Practice
- Use only 3 V coin cells; supervise younger students; store batteries securely.
- Insulate sharp LED legs with tape; avoid shorting the cell by keeping copper traces separated.
- Reuse the snap-clip fastener discs; responsibly recycle spent coin cells.
Why this component is great for scalable STEAM kits
The snap-clip stud button combines a fastener and a battery holder in one tactile part, turning “build a circuit” into “close the snap,” which lowers error rates and speeds setup in large groups. With modular accessories and flexible packaging/private label options, it’s an easy backbone for multiple age-appropriate SKUs—all tightly aligned to the product’s core feature: a simple, reliable clip that makes electricity visible.
