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.
