AI Overview
Reed switches are normally-open magnetic switches that close when a magnet is nearby—great for door/drawer sensors, rotation sensing, and simple on/off magnetic triggers.
Bare reed switches (for custom wiring)
- Reed Switch ($4.55) — basic glass-style reed switch for breadboards/prototyping.
- Reed Switch - Insulated ($7.50) — encapsulated/insulated for a more durable build than a bare glass reed.
Modules / breakouts (easier microcontroller hookup)
- Reed Switch Module ($4.35) — simple module with digital output (DO) style hookup.
- Standard mini Reed Switch Module ($7.80) — compact module form factor.
- LilyPad Reed Switch ($14.85) — designed for e-textiles/LilyPad sewing-style projects.
Door/window style magnetic contact sets (pre-housed)
- Magnetic contact switch (door sensor) ($5.05) — ABS housing with separate magnet piece; ideal for doors/windows/drawers.
- Magnetic Door Switch Set ($9.55) — reed switch assembly specifically aimed at door/drawer open detection.
- Magnetic Switch ($7.90) — housed sensor + magnet; triggers at roughly ~1 cm proximity.

Tactile Button switch (6mm) x 20 pack
·
Little clicky switches are standard input "buttons" on electronic projects. These work best in a PCB but can be used on a solderless breadboard as shown in this tutorial. The pins are normally open (disconnected) and when the button is pressed they are momentarily closed.They come in a pack of...
Fermion: 4-Bit Level Translator (Breakout)
After purchasing an open-source product that is not electrical level compatible, you may find that your sensor cannot work normally or even is easy to be damaged because the level of the sensor and your controller are not compatible. Apart from the poor experience you encountered, this also cause...
Opto Interrupter IRT9608 DIP-4
This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object passes between the uprights, breaking the beam. Used for many applications includin...
REV Robotics SRS Programmer
·
This handheld tool configures REV Smart Robot Servos (SRS) and tests standard RC servos without needing a separate controller. It is built for quick setup at the bench, in the workshop or in a competition toolkit.For SRS units, it gives direct access to operating modes such as continuous rotation...
NeoPixel Addressable 1111 LEDs (1.1mm x 1.1mm) - 50 Strip
·
Incredibly tiny 1111-size (1.1mm × 1.1mm) individually addressable RGB NeoPixel LEDs for creating ultra-compact or high-density smart LED designs. These are the same integrated LED technology used in NeoPixel strips and pixels, but at a fraction of the size — 20× smaller than standard 5050 NeoPix...
MicroMod STM32F405 Processor Board
·
This compact MicroMod processor board adds an STM32F405 to a compatible MicroMod Carrier Board, giving your project an ARM® Cortex®-M4 32-bit RISC core in a small, swappable M.2 module.The bevelled edge connector keys into the MicroMod M.2 socket and is secured with the screw supplied with MicroM...
