Small Sealed Switch
D4E-@N
Slim and Compact Switch with Better Seal
and Ensuring Longer Service Life than D4E
• Flat springs with an improved lever ratio of the built-in switch ensure smooth snap action and long life expectancy.
• Protection cover protects the built-in switch from dust and oil.
Plunger incorporates a tough seal cap that lasts for a long time.
• 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).
• Minute load model with gold cladding is optimal for electronic
control.
• Molded terminal types as well as molded terminal types with operating indicator lamps are available for screw terminal systems.
• No difference in mounting pitch and characteristics between
D4E-@N and D4E models.

Ordering Information
■ List of Models
Note: 1. When ordering, specify the current type by replacing the blank box of the model number with 0 for AC connector or 1 for DC connector.
2. Approved by UL and CSA.
3. For the plunger and lever actuator models, the NC and NO terminal indicators are reversed.
4. Cold tolerance specifications are available for actuator models with an A, B, C, G, or H in the model number. When ordering, add C to
the model number.
For example: D4E-1A20N → D4E-1A20N-C
