Mini Micro Slide Switch, 3-Pin SPDT Toggle Switch for Arduino, Breadboard, and DIY Electronic

Mini Micro Slide Switch – 3‑Pin SPDT Toggle for Arduino, Breadboard & DIY Projects
A compact, low‑profile slide switch that snaps easily onto standard 0.1 in (2.54 mm) breadboard rows. With a single‑pole‑double‑throw (SPDT) design, the switch toggles between two distinct circuit paths (ON‑ON) while the middle pin provides a common connection. The metal sliders are rated for 10 A @ 125 V (AC) and 5 A @ 30 V (DC), making the part robust enough for hobby‑level power handling yet small enough to fit into tight prototyping spaces.

What students learn – By wiring this switch into an Arduino or simple LED circuit, learners explore fundamental concepts such as signal routing, debouncing, and state‑based programming. They practice reading schematics, using a multimeter to verify continuity, and troubleshooting open/closed contacts. The hands‑on experience bridges theory (binary logic, Boolean control) with tangible hardware, reinforcing concepts from physics, computer science, and engineering.

Key features & STEAM benefits

• 3‑pin SPDT configuration (ON‑ON) with a centered common terminal
• Ultra‑small 6 mm × 3 mm footprint; fits directly on a breadboard without soldering
• Gold‑plated contacts for reliable low‑resistance switching
• Rated 10 A / 125 V AC, 5 A / 30 V DC – safe for most classroom projects
• Transparent housing for easy visual inspection of the switch position

Because it merges mechanical motion with electronic control, the Mini Micro Slide Switch is an ideal STEAM tool: it invites students to prototype interactive devices, program microcontrollers, and iterate designs rapidly. Its durability and plug‑and‑play simplicity mean less time troubleshooting hardware and more time exploring creative, interdisciplinary projects—from smart wearables to automated garden sensors.
