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.

GENERAL INFORMATION

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

).
