How to select the best slide switch for your application
Slide switches are one of the older technologies available for selecting, making, or breaking an electrical circuit. However, due to their purely electromechanical nature, they remain popular as low cost and reliable means of controlling or interacting with some aspect of a machine or process. Cathy Zhao, Global Product Manager, Littelfuse discusses.
