MICRO SWITCH Heavy-Duty Limit Switch, HDLS Series

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.

Boss-and-socket

head design for secure

head-to-body retention.

Tracking interchangeability

of actuator levers for single-

and double-pole switches,

plug-in and non-plug-in.

Exclusive teller tab ensures

proper torque. When it cannot

be moved, the lever is tight

enough to prevent

slippage.

Twin shaft seals for an

extra measure of

protection. Optional

ﬂuorocarbon or

ﬂuorosilicone seals.

Front mounting and interchangeability of single- and double-pole switches,

plug-in and non-plug-in with one another and with other switch brands.

Domestic and international

conduit threads.

Rugged, corrosion-

resistant zinc head and

body are phosphate

treated and epoxy

coated.

Diaphragm seal

for exta measure

of protection.

303 stainless steel operating shaft

on sintered bronze bearing for

enhanced mechanical life and operational reliability.

Self-lifting pressure

plate terminals save

wiring time.

Easily identiﬁed

grounding terminal

(inside) for compliance

with regulatory standards.

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.

Each switch has four mounting holes; two “through” holes for front mount, and

two tapped holes in back for rear mount

Dual bearings deliver

enhanced mechanical life.

Superior design of plug-in

terminal between switch body

and receptacle maintains electrical

continuity in harsh conditions

of temperature extremes,

equipment vibration, and shock.

Field adjustable operating head

(CW and CCW, CW or CCW)

matches switch to the application.
