MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series
SPECIAL APPLICATIONS
High Capacity Limit Switch
Features
• High dc current ratings
• 20 A rating at 120 Vac (single pole)
• Plug-in or non-plug in
• Positive retention lever arm
• High resistance to seismic shock
This series has a wide gap contact block
that handles a higher make/break dc
load. In addition, a special lever arm has
a serrated shaft hole and a cap screw
with locking nut for attaching the lever to the rotary shaft.
This assures a firm grip on the operating shaft and positive
retention of the lever adjustment.
The need for precise operation, coupled with challenging
environmental conditions places rigid demands on any
control. Honeywell’s products are intended to satisfy these
demands with its high capacity HDLS, designed to perform
reliably under these conditions.
