FEATURES
DESCRIPTION
Honeywell’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 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.
They are ideal for many applications with demanding indoor
and/or outdoor environments, where they may be subjected
to shock or vibration from equipment, temperature extremes,
dust, splashing water, coolant, and/or hose-directed water.
• NEMA 1, 3, 4, 4X, 6, 6P, 12, 13 and IP65/66/67
environmental sealing
• NEMA/IP sealing features twin shaft seals for an extra
measure of protection
• Rugged, corrosion-resistant zinc head and body are
phosphate treated and epoxy coated
• Diaphragm seal between head and body provides an extra
measure of protection
• Multiple connectivity options for international applications
• Fluorosilicone seals available for low temperature
applications, and fluorocarbon seals available for chemically
harsh environments and higher temperature applications
• Secure head-to-body retention with the head in any one of
four positions 90° apart
• Self-lifting pressure plate terminals saves wiring time
• Wide variety of actuators, switch options, and head styles
• Rotary actuated heads are field adjustable for CW actuation,
CCW actuation, or both
• Silver or gold-plated contacts
• Plug-in and non plug-in bodies have identical operating
characteristics and are dimensionally interchangeable

DIFFERENTIATION
• Sintered bronze bearing on 303 stainless steel operating
shaft for enhanced mechanical life (up to 50 million
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

Figure 1. MICRO SWITCH HDLS Series Features and Options
303 stainless steel operating shaft
on sintered bronze bearing for
enhanced mechanical life and operational reliability.
Field adjustable operating head
(CW and CCW, CW or CCW)
matches switch to the application.
Tracking interchangeability
of actuator levers for single-
and double-pole switches,
plug-in and non-plug-in.
Dual bearings deliver
enhanced mechanical life.
Twin shaft seals for an
extra measure of
protection. Optional
fluorocarbon or
fluorosilicone seals.
Boss-and-socket
head design for secure
head-to-body retention.
Superior design of plug-in
terminal between switch body
and receptacle maintains electrical
continuity in harsh conditions
of temperature extremes,
equipment vibration, and shock.
Self-lifting pressure
plate terminals save
wiring time.
Easily identified
grounding terminal
(inside) for compliance
with regulatory standards.
Exclusive teller tab ensures
proper torque. When it cannot
be moved, the lever is tight
enough to prevent
slippage.
Diaphragm seal
for exta measure
of protection.
Unique, all-metal drive
train for consistent operating
characteristics even at high
temperature; lasts longer
(without the need for
frequent adjustment) than
drive trains with plastic parts.
Rugged, corrosion-
resistant zinc head and
body are phosphate
treated and epoxy
coated.
One piece flat gasket: seals better than gaskets that go around
curves and corners. Does not contact the terminals pins to reduce
possibility of fluid migration.
Domestic and international
conduit threads.
Front mounting and interchangeability of single- and double-pole switches,
plug-in and non-plug-in with one another and with other switch brands.
Each switch has four mounting holes; two “through” holes for front mount, and
two tapped holes in back for rear mount

ASSEMBLY MODIFICATIONS • ROTARY
Momentary action rotary switches can be furnished in other
than the normal assembled conditions. To specify modifica-
tions, add the numbers shown below to the catalog listings.
Modification number suffixes are:
1
Clockwise actuation only
2
Counterclockwise actuation only
3
Shaft to right of switch front
4
Shaft to left of switch front
5
Shaft to back of switch
7
Indicator light wired to NC circuit
For example,
Catalog listing LSA1A23 is an LSA1A switch adjusted for coun-
terclockwise actuation only. The operating shaft is to the right
side of the switch when viewing it from the front (label side).
No lever.
Catalog listing LSA8A7 is an LSA8A switch with the 240 volt
indicator light wired to the NC circuit. No lever.

PLUG-IN VS. NON-PLUG-IN MODELS
Honeywell HDLS limit switches are offered in two styles: non-
plug-in design and plug-in design. With plug-in construction,
the wiring and conduit connection is made to the base recep-
tacle. This feature reduces downtime as the plug-in unit can
be removed and replaced without disconnecting the wiring or
conduit connections to the switch.
