The focus of this article is to investigate current development status of laser sensing technology and its application on switches. Laser sensing technology uses laser beam as the light source for detection. This technology could be applied to high sensitivity requiring non-contact sensing switches. Because of the monochromatic and coherence nature and high directivity property of laser lights, the accuracy and stability of sensing could be improved, leading to creation of a new area of sensing. In order to achieve high accuracy requirement and reduce misjudgments of sensing, this study will focus on the stability of optical modules and the anti-interference of noise suppression circuits. As to the experiment design, it will be divided into two parts: optical module development and circuit design. Furthermore, the advantages of laser sensing will be analyzed. Applications and future development trends will be proposed through experimental results to create a new realm of sensing and increase the value of its industrial applications.
