ASSEMBLY MODIFICATIONS • ROTARY
Momentary action rotary switches can be furnished in other
than the normal assembled conditions. To specify modifica-
tions, add the numbers shown below to the catalog listings.
Modification number suffixes are:
1 Clockwise actuation only
2 Counterclockwise actuation 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 NC circuit
For example,
Catalog listing LSA1A23 is an LSA1A switch adjusted for coun-
terclockwise actuation only. The operating shaft is to the right
side of the switch when viewing it from the front (label side).
No lever.
Catalog listing LSA8A7 is an LSA8A switch with the 240 volt
indicator light wired to the NC circuit. No lever.
PLUNGER ASSEMBLY MODIFICATIONS
Add the following modification numbers to the catalog listing
in the plunger switch:
3 Side plunger to right of switch front
4 Side plunger to left of switch front
5 Side plunger to back of switch
6 Roller on top plungers perpendicular to mounting sur-
face
7 Light on indicator versions wired to NC circuit
8 Roller on side plungers in vertical position
For example,
Catalog listing LSF1A3 is an LSF1A switch with the side roller
plunger to the right side.
PLUGIN VS. NONPLUGIN MODELS
Honeywell HDLS limit switches are offered in two styles: non-
plug-in design and plug-in design. With plug-in construction,
the wiring and conduit connection is made to the base recep-
tacle. This feature reduces downtime as the plug-in unit can
be removed and replaced without disconnecting the wiring or
conduit connections to the switch.
