Description

The DFRobot Gravity Digital Self-Locking Switch is a digital input module that functions as a latching power switch. It utilizes a mechanical self-locking mechanism where a single press toggles the output between a stable HIGH (ON) and LOW (OFF) state, eliminating the need for software debouncing or state maintenance. The output is a clean digital signal compatible with standard microcontroller GPIO pins.

Designed for seamless integration into the DFRobot Gravity ecosystem, the module features a PH2.0-3P connector, ensuring reliable connections and preventing reverse polarity. The PCB employs immersion gold surface finish, enhancing solderability and long-term durability in prototyping and educational environments. Its compact footprint allows for easy incorporation into control panels and project enclosures.

Key Features

  • Self-Locking Toggle Mechanism: Maintains its ON or OFF state without continuous user pressure, providing reliable power control.
  • Broad Voltage Compatibility: Operates from 3.3V to 5V logic levels, making it suitable for a wide range of development boards including Arduino, ESP32, and Raspberry Pi.
  • Gravity Standard Interface: Uses the 3-pin PH2.0 connector for foolproof, tool-free connection to Gravity-compatible shields and sensors.
  • Durable Construction: PCB with immersion gold plating offers excellent oxidation resistance and reliable solder joints.
  • Compact Form Factor: Small dimensions enable integration into space-constrained projects and control panels.
  • Digital Output: Provides a clean, debounced digital signal directly readable by microcontroller input pins.

Applications

  • Master power switch for Arduino or Raspberry Pi project enclosures.
  • Manual override or emergency stop control in mechatronics and robotics.
  • User input interface for toggling system states in interactive installations.
  • Bench-top power control for prototyping and testing circuits.

Frequently Asked Questions

How does the self-locking mechanism work?

The switch uses a latching (bistable) mechanism. A single press changes the output from LOW to HIGH (ON), and the next press changes it back from HIGH to LOW (OFF). It physically locks into each state, so no software is needed to maintain the state, unlike a momentary push button.

What is the operating voltage range, and how do I power it?

The module operates from 3.3V to 5V DC. Connect the VCC pin to your system's 3.3V or 5V rail, GND to ground, and the SIG (signal) pin to a digital input pin on your microcontroller. The included Gravity 3-pin cable simplifies this connection.

Is this switch compatible with Raspberry Pi or only Arduino?

It is fully compatible with both. The 3.3V logic level is safe for Raspberry Pi GPIO. The digital output signal can be read directly by any standard GPIO pin configured as an input on Raspberry Pi, Arduino, ESP32, or other 3.3V/5V logic microcontrollers.

What is the purpose of the Gravity 3-pin interface?

The Gravity 3-pin PH2.0 interface is a DFRobot standard for quick, tool-free connections. It ensures correct pin alignment (VCC, GND, SIG) and allows daisy-chaining with other Gravity modules when used with a compatible shield, speeding up prototyping.
