Open the catalog to page 1Snap-action switches S826 Series Dual changeover switches with positive opening operation and wiping, double-break contacts Schaltbau S826/S926 series dual changeover switches feature positive opening operation which guarantees the forced disconnection of contacts even when they have become welded together due to a short-circuit. The contact bridges of the snap-action switches are galvanically isolated allowing two separate load circuits with independent voltage levels to be controlled simultaneously. Wiping, double-break contacts ensure high reliability even at low electrical loads....
