Collision Switch Module

Introduction

The Crash sensor is a miniature snap-action switch. It is also known as micro switch, an electric switch activated by a small physical force.

feature

• Special module with ports compatible with the expansion board of sensor.
• Output low level when the module is activated; keep outputting high level at the state of release.
• Applied in the detection of collision and touching impact.
