Check up to five results to perform an action.



Snap-action contact with approved direct opening operation certification .
Maintenance, seal, and resistance to shock increased and direct opening mechanism added.
Three-conduit switches and 2NC switches are also available.
  • Direct opening mechanism (NC contacts only) added to enable opening contacts when faults occur, such as fused contacts.
  • Wide standard operating temperature range: –40°C to 80°C (standard type).
  • Safety of lever settings ensured using a mechanism that engages a gear between the operating position indicator plate and the lever.
  • Equipped with a mechanism that indicates the applicable operating zone, as well as push-button switching to control left and right motion.
  • Approved standards: UL, CSA, EN (TÜV), SUVA, BIA, and CCC.
  • Head seal structure strengthened to improve seal properties (TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13).
  • Models with gold-plated contacts added to the series to enable handling microloads.
Note: Contact your sales representative for details on models with safety standard certification.

Note: In addition to the above models, models compatible with the previous D4B Switches (with standard rotary levers) are available. Model number examples: D4B-1x1RN(Pg13.5) or D4B-2x1RN(PF1/2)

Ordering Switches

Because the D4B-xN employs a block mounting construction, parts may be ordered as a complete assembled set or individually as replacement parts. Switches ordered as sets are assembled before shipping.
Note: Do not order combinations of only a Side Rotary Lever and Head or a Side Rotary Lever and Switch Box.
