The LSN3K is a heavy-duty limit switch from the MICRO SWITCH™ HDLS series, featuring a side rotary actuator with maintained contact functionality, where clockwise rotation actuates the switch and counter-clockwise rotation resets it. It is a non-plug-in model constructed with a 0.5-inch NPT conduit entry, silver contacts, and SPDT double break circuitry. This switch is designed to operate reliably within a temperature range of -1 °C to 121 °C. The rugged, corrosion-resistant zinc body and all-metal drive train ensure durability in demanding indoor and outdoor applications. Common uses include machine tools, material handling equipment, and various electromechanical structures.
