The LSQ300 is a heavy-duty sequential contact limit switch from the MICRO SWITCH™ HDLS series. It features DPDT circuitry where Pole 1 operates before Pole 2, with a momentary action. This model is designed with a plug-in body, silver contacts, and a 0.5-inch NPT conduit connection, operating within a temperature range of -12 °C to 121 °C. The plug-in construction greatly reduces downtime by allowing the switch component to be replaced in seconds without disturbing the base receptacle's wiring. Its modular and robust design makes it ideal for demanding industrial applications requiring reliable, sequential operation.
