The SW-520D is a simple, robust metal ball tilt switch module ideal for basic orientation and vibration detection in Arduino, Raspberry Pi, and other microcontroller projects. It functions as a normally-open switch that closes when tilted with the leads pointing down, providing a digital on/off signal.

Features

  • Simple Normally-Open Tilt Switch: Closes circuit when oriented with leads pointing downwards.
  • Robust Construction: Sealed in shrink tubing to prevent short circuits and ensure durability.
  • Low-Power Operation: Maximum current rating of 30mA, suitable for direct MCU input.
  • Wide Temperature Range: Operates reliably from -40°C to +80°C.
  • Compact Form Factor: Small 13.2mm length with 2.54mm pitch spacing for easy PCB integration.

Description

The SW-520D tilt switch utilizes a conductive metal ball within a sealed tube. When the module is oriented so its leads point downward, the ball rolls onto two internal contact poles, closing the circuit and acting as a simple mechanical switch. This provides a straightforward digital signal for detecting tilt, vibration, or basic orientation changes without the complexity of an analog accelerometer.

Designed for reliability in varied environments, the module is insulated with heat-shrink tubing and rated for an extended operational life. Its simple on/off output makes it compatible with any digital input pin on platforms like Arduino, ESP32, or industrial PLCs, requiring minimal signal conditioning.

Key Features

  • Metal Ball Roller Mechanism for reliable contact closure.
  • Insulated Shrink Tubing Housing prevents shorts and offers mechanical protection.
  • High Durability with a life cycle of up to 200,000 actuations.
  • Broad Operating Voltage Range compatible with 3.3V and 5V logic systems (max 20V).
  • Low Contact Resistance of less than 10 ohms ensures a clean signal.
  • Compact and Lightweight design for space-constrained applications.

Applications

  • Simple orientation detection in DIY robotics and RC models.
  • Vibration or tamper detection in basic security devices and alarm systems.
  • Tilt sensing in educational electronics kits and interactive toys.
  • Leveling or tip-over detection in small appliances and portable instruments.

Frequently Asked Questions

What is the output signal type of the SW-520D sensor?

The SW-520D provides a simple digital on/off signal. It acts as a normally-open switch. When the module is tilted with its leads pointing downward, the internal metal ball shorts the contacts, closing the circuit and pulling the connected MCU pin to ground.

What is the maximum voltage and current I can use with this tilt switch?

The module has a maximum contact rating of 20V DC and a maximum current of 30mA. For use with microcontrollers like Arduino (5V) or ESP32 (3.3V), a pull-up resistor (e.g., 10kΩ) is typically used on the signal line, and the switch current will be minimal and well within these limits.

How do I wire the SW-520D module to an Arduino?

Connect one lead of the SW-520D to a digital input pin on the Arduino (e.g., D2). Connect the same lead, via a 10kΩ resistor, to the Arduino's 5V pin (this is the pull-up). Connect the other lead of the sensor to GND. The pin will read HIGH when level, and LOW when tilted.

Can this sensor measure angle or just detect tilt?

The SW-520D is a basic threshold detector, not a precision inclinometer. It detects when it is tilted beyond a point where the ball rolls onto the contacts (approximately when the leads are pointing down). It cannot provide a specific angle measurement, only a binary tilted/not-tilted state.
