mercury switch/Tilt Switch 5mm

The mercury switch/Tilt Switch 5mm is a small two-lead switch that opens or closes a circuit depending on its angle. When the switch is tilted, its internal contacts change state, so a microcontroller can tell whether an object is upright, tipped over or being moved. It is a simple, low-cost way to add tilt and orientation sensing to a project.

mercury switch/Tilt Switch 5mm Specifications

• Type: tilt (orientation) switch
• Size: 5 mm
• Leads: 2, through-hole
• Output: on/off contact, works like a simple switch
• Interface: any digital input with a pull-up resistor

mercury switch/Tilt Switch 5mm Applications

• Tilt and tamper alarms
• Detecting when a device falls over or is turned upside down
• Motion-activated toys, games and lights
• Learning digital inputs with Arduino and ESP32

What's in the Box

• 1 × 5 mm tilt switch

Tip: Connect one lead to a digital pin with the internal pull-up enabled and the other to GND, then add a short debounce delay in code because the contacts can flicker as the switch moves. If the switch contains mercury, do not break it, and dispose of it as hazardous waste.
