What is the difference between one-side operation and both-side operation in Limit Switches?
With one-side operation, Switches will only operate when the lever is pushed in one direction, left or right. They will not operate when it is pushed in the other direction. With both-side operation, Switches will operate when the lever is pushed in either direction.
One-side operation Switches operate as shown in the following figures.
