Five 12mm square tactile switches with coloured caps on small PCBs

NuoTo

NuoTo 5pcs 12x12mm Key Module Switch with Cap for Arduino Raspberry Pi

SKU CH-ZG1C-HSFZ4

Pack of five 12 mm tactile switch modules with caps, 3.5–5 V digital output for microcontroller and Raspberry Pi projects

  • Five tactile switch modules ready for microcontroller projects
  • 12 mm square actuator with integrated key cap for comfortable pressing
  • Digital high-level output when pressed simplifies code logic
  • Operates from 3.5 V to 5 V matching common logic levels
  • Three-pin S V G interface connects directly to Arduino or Raspberry Pi

Five tactile switch modules for microcontroller

This pack contains five 12 mm key modules with integrated caps and a 3-pin digital output. Each board measures 11 by 22 mm and operates from 3.5 to 5 V, delivering a high level when pressed and a low level when released. The modules are designed for direct connection to Arduino, Raspberry Pi or similar MCU and ARM platforms.

Makers adding simple push-button input

Suitable for hobbyists and students who need momentary tactile switches with pre-soldered caps for quick prototyping. Not suitable for applications requiring analogue output, latching action, surface-mount footprints or higher voltage switching beyond the 5 V logic range.

3-pin digital interface with high-on-press logic

The defining specification is the 3-pin S-V-G interface that outputs a digital high signal on press and low on release at 3.5 to 5 V. This determines compatibility with the target microcontroller GPIO pins and removes the need for external pull-up resistors in most designs.

Questions about this item

How do I choose among the five 12x12mm key modules in the pack?

All five modules are identical 11 x 22 mm boards with a 3.5–5 V supply and a 3-pin S-V-G interface, so any one works the same way on Arduino or Raspberry Pi.

What does the 3.5–5 V supply range mean when the module is wired into a project?

The board powers from 3.5 to 5 V and its output goes high when pressed and low when released, matching the logic levels of common MCUs and Raspberry Pi GPIO pins.

What does the 3-pin S-V-G interface cap in practice?

The three pins carry supply, ground and a single digital output, so the module only reports press or release — no analog levels, no communication protocol, just a clean on/off signal.
