How many limit switches are needed if the cylinders to be synchronized are attached to the same machine member?

When two cylinders drive the same moving member, their motions are tied together. That means the position of the whole assembly changes in unison, so one limit switch placed at the end of travel can reliably indicate the position for both cylinders and trigger the control sequence. Adding more switches would just duplicate the same information without adding synchronization value. If the cylinders acted on separate members, you’d need additional sensing to monitor each location, but for a single shared member, one limit switch is sufficient.
