A157 – IRON MAGNETIC SWITCH

    • A157 – Iron magnetic switch
      When two magnetic pieces are close to each other, the contact will be closed, if it is far apart, the contact will be open (normally closed).
      The contact is only used to connect to the Zone pin of the alarm cabinet, not to open and close other electrical devices such as bells, whistles, lights because it can damage the contacts when a large current flows through.
