Heavy Duty Limit Switches
ROTARY OPERATING HEADS
The head type is designated by the first
three letters in the catalog listing, i.e.,
LSA1A-1A has an LSA standard side rotary
head. See order guides for details. All are
momentary action, except the maintained
contact LSN head.
SIDE ROTARY
LSA — Standard
LSP — Low Differential Travel
LSR — Low Operating Torque
LSH — Low Torque, Low Differential
LSS — Gravity Return
LST — Extra Low Torque
LSL — Sequence Action
LSM — Center Neutral
LSN — Maintained Contact
TOP ROTARY
LSB – High Overtravel
Honeywell MICRO SWITCH Sensing and Control 1-800-537-6945 USA
Overtravel 60 minimum, pretravel 15
maximum, differential travel 5 (single-
pole) and 7 (double-pole) maximum.
Overtravel 68
maximum, differential travel 3 (single-
pole) and 4 (double-pole) maximum.
Overtravel 60 minimum, pretravel 15
maximum, operating torque 1.7 in. lbs.
(0,19 Nm) maximum.
Overtravel
torque 1.7 in. lbs. (0,19 Nm) maximum,
differential travel 3 (single-pole) and 4
(double-pole) maximum.
Operating torque 5 in.-oz.
Operating torque 12 in.-oz.
Delayed action between operation of two
poles, in each direction. Overtravel 48
minimum.
One set of contacts operates on clock-
wise rotation, another set on counter-
clockwise
minimum.
Operation is maintained on counterclock-
wise rotation, reset on clockwise rotation,
and vice versa. Overtravel 20 minimum.
Top rotary actuation is ideal when in-
creased overtravel is required (100 mini-
mum.) Uses same levers as side rotary
switches.

ROTARY LEVERS
Shown below are typical lever series for side
and top rotary switches. Additional versions
are described in the lever order guides.
LSZ51 — Standard Roller Lever (1.5 )
LSZ55 — Offset Roller Lever
LSZ53 — Yoke Roller Lever
Field adjustable to match application needs
Actuation is adjustable for operation clock-
wise, counterclockwise, or in both direc-
tions. Adjusting instructions are cast into the
internal lid of side rotatary heads for conve-
nient reference.
For use with LSN maintained contact
switches.
Levers lock in any position,
360 around the shaft.
