ABSTRACT:
A low cost, tilt switch of simple construction facilitates tamper detection or provides notice of equipment tipping for safety applications. In one example embodiment, a tilt sensor includes an electrically insulative housing, a conductive ball, and two opposing electrical contacts. The switch further includes an arrangement for aligning the two opposing electrical contacts when the tilt sensor housing is formed. The sensor is mountable in a device being monitored for tilt or excessive movement. In one example application, the tilt switch or sensor effects an electrical connection that signals meter tampering when a meter is moved or inverted.
