					GENERAL INFORMATION  
					MICRO SWITCH NT Series toggle switch-  
					es meet severe environment application  
					needs for a rugged, cost-effective toggle  
					switch. Quality construction features in-  
					clude a molded-in elastomer seal be-  
					tween the toggle lever and bushing, and  
					between the cover and case. In addition,  
					the terminal inserts are molded into the  
					high impact strength thermoplastic case.  
					Complete sealing of the switching cham-  
					ber enables NT toggles to comply with UL  
					508, paragraph 13.3 hosedown test.  
					These switches can be used where pan-  
					els are subjected to periodic splash and  
					washdowns, such as are common to food  
					and beverage equipment. They will also  
					withstand exposure to heavy accumula-  
					tions of early morning dew that may con-  
					dense on the control panel in cabs of  
					vehicles left outdoors overnight.

					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
