GENERAL INFORMATION
MICRO SWITCH NT Series toggle switches
are designed to meet severe environment
application needs for rugged, cost-effective
manual switches. These flat base style
products are identical to the stepped
base style in construction and features.

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 switches use silver cadmium oxide
contacts. For other options, contact the MICRO SWITCH Application Center at
1-800-537-6945.
The flat base allows for PC board or con-
nector use for easy wiring/connection.
The flat base NT toggle switches are
provided with quick-connect (spade)
termination. Mating connectors 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).
