Door, Hatch & Latch Position Indication for Marine Applications


Entryway status is a necessity in industrial environments such as power generation facilities and large ships. Heavy-duty limit switches are used to indicate entryway status for a large door or hatch, providing a critical safety factor. Also, hatch, or entryway, indication is used for added security. The main concern for these massive, industrial entryways is whether they are open or closed.
