Introduction; General Features; Warning - PCB Piezotronics IMI SENSORS 685A19 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 patent pending 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.
