Manual Switches  
NR Series  
Sealed Rocker Switches  
FEATURES  
ɀ Completely sealed switching  
chamber  
ɀ Colored removable rockers  
ɀ Choice of flush-panel or above-panel  
mounting  
ɀ Step-design case provides added  
space between terminals to help  
prevent shorting  
ɀ 1, 2 or 4-pole circuitry

GENERAL INFORMATION  
MICRO SWITCH NR Series Rocker Switches meet severe environment application  
needs for a rugged, cost-effective manual switch. They combine the advantages of  
toggle switch circuit versatility with pushbutton control.  
ɀ Spring-loaded actuating mechanism  
provides excellent tactile feedback  
ɀ High impact strength, non-tracking  
case enhances electrical stability  
ɀ Temperature range: 40 to 71°C  
(40 to 160°F)  
ɀ UL recognized, File E12252, Vol. 1,  
Section 44  
ɀ CSA certified, File LR4442  
ɀ CE approved  
Quality construction features include a premolded elastomer seal between the actua-  
tor and bushing and an elastomer cover/case gasket seal. Also, the terminal inserts are  
molded into the high impact strength thermoplastic case.  
Complete sealing of the switching chamber enables compliance with UL 508, para-  
graph13.3 hosedown test. These switches can be used where panels are subjected to  
periodic splash and washdowns, such as are common to food and beverage equip-  
ment. They will also withstand exposure to heavy accumulations of eary morning dew  
that may condense on the control panel in cabs of vehicles left outdoors overnight.  
HOW TO ORDER  
1. To order flush panel mount switches  
without rockers, specify the listings in  
the NR order guides.  
2. To specify above-panel mount  
switches, change the1(after ‘‘NR’’) in  
1NR1, 11NR1, 2NR1, 12NR1, 4NR1, and  
14NR1 listings in the NR order guides  
to 4. Example: 1NR1-2W converts to  
1NR4-2, 11NR1-2 to 11NR4-2.  
For 1NR91, 2NR91, and 14NR91 list-  
ings add 4 (after the ‘‘NR’’) to specify  
the above panel mount version. Exam-  
ple: 1NR91-2 becomes 1NR491-2.  
3. To order rockers, specify listings in  
the 12PA rocker order guide.

MICRO SWITCH NT Series toggle switch-  
es and NR Series rocker switches are  
designed to meet severe environment ap-  
plication needs for rugged, cost-effective  
manual switches. These flat base style  
products are identical to the stepped  
base style in construction and features.  
The flat base allows for PC board or con-  
nector use for easy wiring/connection.  
The flat base NT toggle switches and NR  
rocker switches are provided with quick-  
connect (spade) termination. Mating con-  
nectors are available.

TERMINAL CIRCUIT IDENTIFICATION  
Terminal identifications are referenced in  
the order guides to indicate which circuits  
are made in each toggle position (e.g.  
‘‘1-2’’ refers to circuit closure through ter-  
minals 1 and 2).  
Application Note: Honeywell MICRO SWITCH does not recommend the use of silver  
cadmium oxide switch contacts in non-arcing loads. Non-arcing loads are generally  
loads less than 12 volts and/or 0.5 amp. NT/NR switches use silver cadmium oxide  
contacts. For other options, contact the MICRO SWITCH Application Center at  
1-800-537-6945.
