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).
