MICRO SWITCH™ Heavy-Duty Limit Switches
HIGH TEMPERATURE/CHEMICAL RESISTANT
SWITCHES
Completely uorocarbon (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 re-resistant synthetic uids. In addition to most all uids,
the FC-sealed switches may be used with such industrial uids
such as Cellulube, Fyrquell, Houghto-Safe, Pydraul, and other
special cutting and hydraulic uids. The additional FC seals also
promote longer operating 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.
To order, insert the additional letters Y and C in the appropriate
places in the standard catalog listing, as shown below:

SPECIAL OPTIONS
LOW TEMPERATURE SWITCHES
All forms of HDLS limit switches are also available in low-tempera-
ture construction. Design features include uorosilicone diaphragm,
shaft seals, and external booth seal (where applicable). If pre-wired
with a cable, low temperature limits are
-10 °C [14 °F] ex and -30 °C [-22 °F] non-ex.

MICRO SWITCH™ Heavy-Duty Limit Switches
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 rm
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.

SPECIAL APPLICATIONS
GRAVITY RETURN SIDE ROTARY SWITCHES
(LSS)
LSS1H gravity-return, side-rotary switches have no return spring
mechanism. The weight of the actuating lever must provide the
force to restore it to the free position. The 5 in-oz. max. operating
torque is useful in conveyor applications since it enables opera-
tion by small or lightweight objects. Because the head is unsealed,
the LSS1H is classied 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 re-
turn 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™ Heavy-Duty Limit Switches
Fully potted MICRO SWITCH™ HDLS heavy-duty limit switches provide an extra degree of protection in
harsh environments by sealing the basic switch cavity with epoxy. These switches are the same as the non- plug-in
HDLS except that the entire switch cavity is lled with epoxy in addition to the conduit entrance. The fully potted
HDLS switches are pre-leaded, with either cable or connectors.
• Excellent sealing capability for harsh-duty food and beverage wash downs and severe machine tool environ-
ments
• Diaphragm sealing
• 12 inch STOOW-A cable (other lengths available) or connector version
• Cable versions: NEMA 1, 6, 6P, 12
• Connector versions: NEMA 1, 6, 6P, 12, 13
• All uorocarbon seals (low temperature uorosilicone seals available)
• UL, CSA, CE, CCC
ALSO AVAILABLE
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 dockside lo-
cations. 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 uorocarbon to
provide excellent chemical resistance and to withstand operating temperatures up to 121 °C [250 °F] and pressur-
ized steam cleaning. Pre-leaded and epoxy-lled versions also available.
• Corrosion-resistant stainless steel non-plug in body, head, and rotary shaft
• Stainless steel levers
• Fluorocarbon seals (low temperature uorosilicone seals available)
• NEMA 1, 3, 3R, 4, 4X, 6, 6P, and 13
