Introduction; General Features; Warning - PCB Piezotronics IMI SENSORS EX685A09 Installation And Operating Manual

Introduction

The Mechanical Vibration Switch is a shock sensitive mechanism for shutdown of engine or electric motor
powered equipment. This switch uses a patented linear adjustment magnetic latch technology to ensure reliable
operation. Pushing the reset button moves the tripping latch into a magnetically held position. A shock/vibration
will move the magnet beyond this holding position, thus freeing the spring loaded tripping latch to transfer the
contacts and shut down the machinery.
