Limit Switches are generally used to control machinery in industrial applications. They act as a safety interlock and can be used to establish or disrupt electrical connections. The heavy-duty limit switches are the world's most advanced line of micro switches. These switches include boss-and-socket head design for secure head-to-body retention, and unique all-metal drive train for consistent operating characteristics even at high temperature and are therefore often used in machine tools, material handling, packaging, presses, pulp and paper, welding, and PLC interface.

LSN1A Limit Switch from Honeywell comes with captive head, body screws and field adjustable operating modes for reduced inventory. This Honeywell switch offers a complete choice of circuitry and electrical rating options.
