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.
• Silver or gold-plated contacts
• Plug-in and non plug-in bodies have identical operating
characteristics and are dimensionally interchangeable
POTENTIAL APPLICATIONS
• Machine tools
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.
• Automotive machine tools
• Material handling
• Outdoor electromechanical structures
• Balers/compactors
• Conveyors
• Food and beverage
• Power plants
• Off-road equipment
• Agricultural equipment
• Valves
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
• Transportation hubs

PLUGꢀIN VS. NONꢀPLUGꢀIN 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.

MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series
SPECIAL OPTIONS
High temperature/Chemical-resistant Switches
Low Temperature Switches
Completely fluorocarbon (FC)-sealed switches have a full FC
body gasket coving the switch cavity. Rotary types have an
extra FC seal on the operating shaft, while plunger versions
have FC boot seals. They are for use in many applications
where the environment includes fire-resistant synthetic fluids.
In addition to most all fluids, the FC-sealed switches may be
used with such industrial fluids such as Cellulube, Fyrquell,
Houghto-Safe, Pydraul, and other special cutting and hydrau-
lic fluids. The additional FC seals also promote longer oper-
ating life for rotary-actuated HDLS switches in applications
where the temperatures are normally -12°C to 121°C [10°F
to 250°F]. If pre-wired with cable, then temperature limits are
105°C [221°F] dry and 60°C [140°F] wet.
All forms of HDLS limit switches are also available in low-tem-
perature construction. Design features include fluorosilicone
diaphragm, shaft seals, and external booth seal (where appli-
cable). If pre-wired with a cable, low temperature limits are
-10°C [14°F] flex and -30°C [-22°F] non-flex.

MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series
SPECIAL APPLICATIONS
Gravity Return Side Rotary Switches (LSS)
Extra Low Torque Side Rotary Switches (LST)
LSS1H gravity-return, side-rotary switches have no return
spring mechanism. The weight of the actuating lever must pro-
vide the force to restore it to the free position. The 5 in-oz. max.
operating torque is useful in conveyor applications since it
enables operation by small or lightweight objects. Because the
head is unsealed, the LSS1H is classified as NEMA 1. However,
the switch cavity is sealed to protect the switch contacts.
LST1H extra-low torque, side-rotary switches have a low force
return spring and a maximim operation torque of 12 in-oz. It is
rated as NEMA 1 due to an unsealed head. The switch cavity is
sealed to protect the switch contacts.

MICRO SWITCH HDLS switches are also available in all stainless-steel versions. Designed for use in
highly corrosive environments, such as petrochemical plants, food processing plants, shipboard, and dock-
side locations. The type 316 cast stainless steel body is designed to minimize crevices where food particles
could become trapped in water. The actuator, operating head, and screws are also stainless steel. All seals
are fluorocarbon to provide excellent chemical resistance and to withstand operating temperatures up to
121°C [250°F] and pressurized steam cleaning. Pre-leaded and epoxy-filled versions also available.
