The D4E-1D10N is a single-pole double-throw small Sealed Switch with sealed roller plunger actuator, DC connector terminal and NC-NO contact type. One touch connector eliminates need for tedious wiring operations and reduces downtime for wiring and maintenance (models with standard, easy-to-use screw terminals are also available). Protection cover protects the built-in switch from dust and oil. Plunger incorporates a tough seal cap that lasts for a long time. Flat springs with an improved lever ratio of the built-in switch ensure smooth snap action and long life expectancy.
