Magnetic Contacts from
Anyone can boast about their magnetic contacts' quality. But look deep inside the magnetic contact, where human eyes seldom go, and see the quality offered only by SECO-LARM. Step inside, and see the world-wide patented reed switch with a unique deactivated rhodium plating. See the unique glue and epoxy combination. See the advanced engineering and detailed quality control. And understand how SECO-LARM can offer the most reliable contact available anywhere, especially at the lower voltage levels normally used in security systems.
