A small push-button switch module on a breakout board with a built-in pull resistor, so no external resistors are needed. The 3-pin header (signal, VCC, GND) plugs directly into a solderless breadboard or connects via jumper wires to Arduino, Raspberry Pi, and other microcontrollers.
Key Features
- Built-In Resistor – No external pull-up or pull-down resistor required
- 3-Pin Header – Signal, VCC, and GND for easy breadboard connection
- Breadboard Friendly – Mounts directly onto solderless breadboards
- 100,000-Cycle Life – Durable tactile switch
Specifications
- Max Rating: 50 mA at 12 V DC
- Contact Resistance: 50 mΩ max (initial)
- Insulation Resistance: 100 MΩ min (at 250 V DC)
- Dielectric Strength: 250 V AC (50/60 Hz, 1 minute)
- Electrical Life: 100,000 cycles
- Operating Force: 1.80–2.25 N (±0.20 N)
- Operating Temperature: −25 to +105°C
Ideal For
- Arduino and microcontroller input projects
- Breadboard prototyping
- Simple user interface buttons

- 1× 3-Pin Button Key Switch Module
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- solderless breadboard
- A reusable board with connected holes for building temporary circuits without soldering. It matters in beginner kits because students can change wiring quickly and safely while learning how components connect.
