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 switches use silver cadmium oxide
contacts. For other options, contact the MICRO SWITCH Application Center at
1-800-537-6945.
