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. PULL-TO-UNLOCK LEVERS Pull-to-unlock toggle levers prevent acci- dental toggle movement. The knobbed toggle lever must be pulled out approxi- mately .09 in. (2,3 mm) to change posi- tions. Thirteen different locking configu- rations are available. This lever style also has a non-glare matte nickel finish.
