Snap-action contact with certified direct
opening operation certification .
Maintenance, seal, and resistance to
shock increased and direct opening

operating zone, as well as push-button switching to control left
and right motion.
• Head seal structure strengthened to improve seal properties
(TÜV: IEC IP67, UL: NEMA 3, 4, 4X, 6P, and 13).
