MICRO SWITCH™ Commercial-Grade Toggle Switches NT Series Datasheet MICRO SWITCH™ NT Series Commercial-Grade Toggle Switches Honeywell MICRO SWITCH™ NT Series toggle switches meet the need for a rugged, cost-effective toggle switch. Quality construction features include a seal between the toggle lever and bushing, and between the cover and case. These switches are suitable for applications in many demanding outdoor environments, where the panels are sub- jected to vibration from equipment, temperature extremes, dust, splashing water, and/or hose directed water. They are capable of withstanding exposure to heavy accumulations of early morning dew that may condense on the control panel in cabs of vehicles left outdoors overnight. The NT toggle switches with larger standard metal or plastic levers are well suited for gloved-hand operation. Available in both step-base and flat-base styles, the NT Series offers three popular styles of termination: 6-32 screws, solder lugs with 3,0 mm [0.12 in] diameter hole, or 6,35 mm [0.25 in] quick connect terminals. The optional “Easy Start” threaded bushing enables quick alignment of the mounting nut to minimize any cross threading. The panel stand-off with O-ring feature available on some listings eliminates the need for behind-the-panel hardware, provides a uniform panel height, and a panel-to-cover seal. What makes our switches better? NEMA 3, 3R, 4, 13 and IP67/68 environmental sealing for demanding applications UL recognized, CSA certified, and CE certified for global use 1-, 2-, and 4-pole options to meet a variety of circuitry requirements 2- or 3-position maintained and momentary action to meet circuit and actuator requirements Optional step-case design provides added space between terminals to prevent shorting Tough environmental sealing makes harsh environments seem like just another sunny day. ENVIRONMENTAL SEALING • GLOBAL APPROVALS MULTI-CIRCUITS • HIGH PERFORMANCE sensing.honeywell.com 2 SEALED TO NEMA 3, 3R, 4, 13 AND IP67/IP68 FOR GLOBAL USE F Fe ea at tu ur re es s MICRO SWITCH™ NT toggle switches feature a moveable seal between the a an nd d Be Ben ne efit fits s toggle lever and bushing and a completely sealed case to meet NEMA and IP seal ratings. They are suitable for applications in many demanding outdoor environments, where the panels are subjected to vibration from equipment, temperature extremes, dust, splashing water, and/or hose directed water. UL recognized, File E12252, Vol. 1, Section 44, CSA certified, and CE certified for global use Excellent tactile feedback WELL-SUITED FOR GLOVED-HAND OPERATION Spring-loaded actuating mechanism provides excellent tactile feedback for the toggle switch lever. The NT toggle switches with larger standard metal or plastic levers are well suited for gloved-hand operation Locking levers reduce unintended actuation LOCKING LEVERS Optional lever locks (pull-to-unlock) require two separate actions to actuate the switch in order to prevent unintended actuation MINIMIZES INSTALLATION TIME Optional flat base case design with a quick connect terminal pattern mates to a commercial-type connector for plug-and-play connectivity, reducing installation time VARIETY OF CIRCUITRIES AND OPERATING ACTIONS NT Series’ 2- and 3-position, maintained and momentary toggle action, for a breadth of circuitry and actuator requirements. Delivers high performance in a wide range of temperatures: -40 °C to 71 °C [-40 °F to 160 °F] EASILY CONTROLS LOW-VOLTAGE DC APPLICATIONS Toggle switches available with a choice of silver alloy or gold-plated contacts to handle a variety of electrical load requirements INNOVATIVE PRODUCT DESIGN Optional engineered step-design case provides added space between terminals to prevent shorting. Optional panel stand-off with O-ring panel seal eliminates behind-the-panel hardware sensing.honeywell.com 3 Potential Applications AERIAL PLATFORM LIFTS Momentary toggles are used to operate the movement of aerial platform lifts. Toggle can be used to raise & lower, extend & retract and rotate platform or outriggers. PLATFORM LIFTS FOR TRUCKS Used to fold/unfold and raise/lower from a lift gate’s control panel. INDUSTRIAL EQUIPMENT Used in the control panel of overhead cranes and factory floor equipment. RAILROAD LOCOMOTIVES AND MAINTENANCE EQUPMENT Designed into control panels often found in locomotives, rail grinders, tie removal, ballast spreaders, and tampers. CONSTRUCTION EQUIPMENT Used to operate movement of machinery and/or turn on lights, pumps, etc. in road milling, road pavers, trenchers, stump cutting and other construction and mining equipment. Also widely used for remote control of concrete pumping and drilling machines. AGRICULTURAL MACHINERY Used in control panels for harvesting equipment, grain handlers, and grain dryers. sensing.honeywell.com 4 MICRO SWITCH™ Commercial-Grade Toggle Switches Table 1.
