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.
