These switches can be used where panels are subjected to periodic splash and washdowns, such as are common to food and beverage equipment. They will also withstand exposure to heavy accumulations of early morning dew that may condense on the control panel in cabs of vehicles left outdoors overnight. PULL-TO-UNLOCK LEVERS Pull-to-unlock toggle levers prevent accidental toggle movement. The knobbed toggle lever must be pulled out approximately .09 in. (2,3 mm) to change positions. Thirteen different locking configurations are available. This lever style also has a non-glare matte nickel finish. 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.

These flat base style products are identical to the stepped base style in construction and features. The flat base allows for PC board or connector 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 terminals 1 and 2).
