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
