MICRO SWITCH
HDLS Series
Heavy-Duty Limit Switches
DESCRIPTION
Honeywell Sensing and Control’s 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.
