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 (HDLS) 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. They are generally used in machine tools, material handling, packaging, presses, pulp and paper, welding, and PLC interface.

LSA6B Limit Switch from Honeywell offers a wide variety of operating heads and field adjustable operating modes for reduced inventory. This Honeywell switch comes captive heads, body screws and a complete choice of circuitry and electrical rating options.
