Tilt Switches

Tilt sensors and tilt switches

Most alarm sensors watch for impact. A tilt sensor watches for the vehicle changing angle, and that covers a different kind of theft entirely: a car jacked up for its wheels, or winched onto a flatbed. Both are quiet, both are quick, and a shock sensor often never fires.

If you park on a street where catalytic converters and wheels go missing, this is the sensor that matters.

Which type

Mercury switches are the traditional design and the most sensitive. Many jurisdictions now restrict mercury on environmental grounds, so check before choosing one.

Ball bearing switches do the same job mechanically, using a rolling ball instead. No mercury, no restrictions.

Digital sensors measure the change in angle rather than waiting for something to physically move. Fewer false alarms on a sloped driveway or a windy day, and they work in any mounting orientation.

Wire them through a relay

The mechanical switches are rated to switch a circuit, not to power one. Run them through a relay and they'll last.
