MICRO SWITCH™ NT SeriesCommercial-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 thecontrol panel in cabs of vehicles left outdoors overnight.
The NT toggle switches with larger standard metal or plasticlevers 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 crossthreading.
The panel stand-off with O-ring feature available on some listings eliminates the need for behind-the-panelhardware, provides a uniform panel height, and a panel-to-cover seal.
