GENERAL INFORMATION
• Honeywell’sEnclosedBasicSeriesofLimitSwitchesare
usable in many applications. The wide variety of actuators
offered and their robust diecast housing make them ideal for
applications that require reliable switching and performance.
There are several styles of enclosed basic switches, includ-
ing side and flange mounting switches as well high capacity
and double pole type.

2. Boot-sealedandside-mountingswitchesusesealingwash-
ers under screw heads on the sides between switch and
mounting surface on other side to maintain seal.
3. Unsealed, side mounting switches: Use lockwashers under
screw heads on one side; under nut on other side.
4. Connect conduit to conduit opening. Apply conduit sealing if
required by application.
INSTALLATION TIPS
1. Do not lubricate any internal part of the switch. The inter-
nal switch does not require any additional lubrication
2. When installing the switch, ensure that it is not the low
point in the conduit run. Doing so will ensure that con-
densation created in the conduit will not flow into the switch
housing.
3. Do not enlarge the mounting holes on side mounting
switch. Doing so will compromise the internal switching ele-
ment’ssealintegrity.

The lever can be adjusted in two ways. The following process
details how to perform the adjustments.
Adjusting the horizontal position of the lever.
1. Loosentheleverbaseretainingnut,sothattheleverassem-
bly is free to rotate about the axis of the plunger.
2. Rotatethelevertothedesiredposition.Theleverisadjust-
able360degreesabouttheaxis.
3. Once the desired position is reached re-tighten the lever
base retaining nut. The lever base should not be able to
rotate when properly tightend.
Adjusting the vertical position of the lever.

2. Setthepositionofthelevertothedesiredposition.Roller
levers should be positioned so that they are able to actuate
the plunger.
3. Once the desired position is reached re-tighten the lever re-
taining nut. When pushed the lever should act upon the lever
mechanism to actuate the switch.
N18 TYPES
If actuator or basic switch is replaced, the actuator may need
adjustment to duplicate original switch operating point. To adjust
operating point, remove lower seal band from base of seal boot.

unoperated, slowly turn bushing clockwise until basic switch op-
erates. Do not turn further after operating click is heard. Turn
bushing back 1/2 turn. Tighten jam nut on bushing.

WIRING
• Honeywell’sEnclosedBasicSwitcheshaveinternalterminals
that allow for easy wiring and integration.
• Ifasidemountingswitchisbeingwireditispossibleforthe
switch to be mounted in place before wiring takes place. If
a flange mounting switch is being used it is likely that that
the switching and actuator assembly will need to be wired
before mounting switch.
The enclosed basic series switch will have one of two contact
forms available. They will either have a single pole double throw
(SPDT) or a double pole double throw (DPDT) arrangement. The
SPDT uses three terminals to wire a set of Common (C), Normally
Open (NO), and Normally Close (NC) contacts.

according to the contact they connect to. Please refer the
terminal layout section for more information on circuit dia-
grams and terminal screw layout.
