The HDLS series MICRO SWITCH™ heavy-duty Limit Switch for outdoor electromechanical structures. The modular construction allows for a wide variety of actuator styles, operating heads and electrical circuitry options. The plug-in versions greatly reduce downtime on production lines with high actuation rates as replacement of the switch is accomplished in seconds. The base receptacle contains all the wiring and conduit connection while the switching component with operating head easily assembles to the base and is attached with two screws. Sintered bronze bearing on 303 stainless steel operating shaft for enhanced mechanical life (50M actuation cycles) and operational reliability. All-metal drive train for consistent operating characteristics, even at high temperature. Lasts longer (without need for frequent adjustment) than drive trains with plastic parts. Exclusive teller tab ensures proper torque. When it cannot be moved, the lever is tight enough to prevent slippage.
