Switching element ES 538H 1) 3) Slow-action contact element with two direct opening action contacts. Double gap contacts, electrically isolated H-contact bridges for currents from 1 mA to 4 A, silver alloy, gold flashed contact material, screw terminals with selflifting clamp washers. Used for NZ... 1) Slow-action contact element The slow-action contact element has a contact element which opens and closes depending on its actuation speed. 2) Snap-action contact element The snap-action contact element has a contact element which opens and closes regardless of its actuation speed. 3) H-contact bridge The design properties of the H-contact bridge (H-shaped) ensure that these switching elements reliably switch currents from 1 mA (e.g. low current PLCs) to 4 A. EUCHNER position switches marked with this symbol meet the IEC 60947-5-1 requirements for safety position switches with direct opening action contacts. Safety switching elements marked with this symbol are not available as replacement switching elements.
