How to order
Momentary action rotary switches can be
furnished in other than the normal assem-
bled conditions described on the facing
page. To specify modifications, add the
number(s) shown below to the catalog list-
ings. Prices are the same as their counter-
parts shown in the order guide.
Modification number suffixes are:
1
Clockwise operation only
2
Counterclockwise operation only
3
Shaft to right of switch front
4
Shaft to left of switch front
5
Shaft to back of switch
7
Indicator light wired to N.C. circuit
Examples:
Catalog Listing LSA1A23 is an LSA1A switch
adjusted for counterclockwise operation
only. The operating shaft is to the right side
of the switch when viewing it from the front
(label side). No lever.

with the 240 volt indicator light wired to the
N.C. circuit. No lever.
Switches with assembly modifications are
not normally stocked and may extend deliv-
ery leadtimes.

** These switches have either gold plated or gold cross point contacts. Cross point contacts improve high
reliability of contact make when particle contamination is a problem or low energy loads must be carried.

Levers for Rotary Actuated Switches
Levers for use with side or top rotary actuat-
ed switches are available in a wide choice of
sizes and materials, as shown in the order
guides on the following pages. Rollers may
be on either side of the lever to best match
the external actuating mechanism. They
permit a wide range of cam tracking possi-
bilities (see drawings below).
LSZ51
standard rollers and
LSZ55
offset
roller levers have a fixed 1.5 inch (38,1 mm)
radius.
LSZ53
yoke roller levers are used with side
rotary maintained switches, where a reci-
procating actuator operates the switch in
one direction and reverses it when moving
in the other direction.
LSZ52
adjustable length roller levers are
universally adaptable to many application
needs.
LSZ54
rod levers may be formed by the
user. The hub permits adjusting of lever
length. Also available in flexible versions.
LSZ61
is an adjustable loop lever.
For lever order guides, refer to the following
pages.
