Generic Mercury Tilt Switch - Pack of 1 - Digital Output
This Mercury Tilt Switch is a basic digital sensor compatible with 3.3V and 5V logic systems like Arduino and Raspberry Pi. It provides a simple on/off output signal based on its physical orientation, triggered by the movement of a mercury bead within a sealed glass envelope.
Features
- Digital ON/OFF output compatible with microcontrollers.
- Low-voltage operation from 3.3V to 5V DC.
- Compact dimensions: 4mm diameter, 35mm length.
- Sealed glass envelope prevents contact oxidation.
- Simple, non-mechanical sensing via mercury bead movement.

The Mercury Tilt Switch operates on a fundamental physical principle: a small bead of mercury moves within a sealed glass envelope under the influence of gravity. When the switch is tilted to a specific angle, the conductive mercury bridges a set of internal contacts, closing an electrical circuit and providing a digital HIGH signal. Tilting it back moves the mercury away, breaking the circuit and returning a digital LOW signal.
This design offers inherent advantages for basic orientation detection. The sealed environment protects the contacts from oxidation and contamination, ensuring long-term reliability without contact wear. The absence of snapping mechanical parts makes the switch silent in operation and resistant to chatter. It is a simple, cost-effective solution for detecting tilt or basic vibration in low-power electronic projects.
