KY-017 Mercury Tilt Switch Module

The KY-017 Mercury Tilt Switch module is a switch that responds to movement. It uses a small mercury ball that completes the circuit when the module is tilted.

This module consists of a mercury switch, a 680Ω resistor and a LED that will light up when tilt is detected. The mercury ball will open/close the circuit when the module is rotated.

Operating Voltage    3.3V ~ 5.5V
