The 4-Pin Mini Push Button Tactile Switch is the most common input component for breadboard prototyping and PCB design. At Electrapac, we provide these high-quality, "clicky" switches to ensure your projects respond instantly to every press.

Product Overview

These are Momentary Tactile Switches, meaning they only complete the circuit while they are being physically pressed. Once released, the internal spring snaps the connection open again. With a standard 6mm x 6mm footprint, they are designed to fit perfectly into the 0.1" pitch of a standard breadboard or perf-board.

Key Features for Electrapac Customers

• Tactile Feedback: Features a distinct "click" sound and feel when pressed, providing physical confirmation that the button has been activated.

• 4-Pin Stability: While it functions as a simple 2-terminal switch, the 4-pin design provides extra mechanical stability when soldered to a PCB or plugged into a breadboard.

• Breadboard Friendly: The pins are spaced and slightly "kinked" to grip the holes of a breadboard firmly, preventing them from popping out during testing.

• Long Cycle Life: Rated for over 100,000 presses, making them durable enough for frequently used reset buttons or user-interface controls.

• Universal Compatibility: Works with any 3.3V or 5V logic system, including Arduino, Raspberry Pi, ESP32, and PIC microcontrollers.

  Wiring Tip: Understanding the 4 Pins

  A common mistake is thinking all 4 pins are independent. In reality, the pins are connected in pairs. Usually, Pins 1 & 2 are internally connected, and Pins 3 & 4 are internally connected. When you press the button, it bridges the gap between the two pairs.

  Pro Tip: For a clean digital signal on your Arduino from www.electrapac.com, always use a 10kΩ Pull-Up or Pull-Down resistor (or use the internal INPUT_PULLUP code) to prevent "floating" pin readings when the button isn't pressed.

  Primary Applications

  • User Input: Selecting modes, starting/stopping motors, or navigating menus on an LCD.

  • Reset Buttons: Adding an external reset trigger for your microcontroller.

  • Game Controllers: Building DIY joysticks or handheld gaming consoles.

  • Alarm Triggers: A simple "Panic Button" or door-tamper detection switch.
