MICRO SWITCH HDLS Series Heavy-Duty Limit Switches DESCRIPTION Honeywell Sensing and Controls MICRO SWITCH heavy-duty limit switches modular construction allows for a wide variety of actuator styles, operating heads, and electrical circuitry options. The plug-in versions greatly reduce downtime on high production lines 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.
