Item 2.01   Completion of Acquisition or Disposition of Assets.

     On  January  29,  2010,  Bel  Fuse  Inc.,  a New  Jersey  corporation  (the
     "Registrant"),   completed  its  acquisition  of  all  of  the  issued  and
     outstanding  capital stock (the "Stock") of Cinch Connectors,  Inc. ("Cinch
     U.S.") and Cinch  Connectors  Limited ("Cinch  U.K.").  Pursuant to a stock
     purchase  agreement,  dated as of December 28, 2009,  among the Registrant,
     Safran USA, Inc.  ("Safran U.S.") and Safran UK Limited ("Safran U.K." and,
     together with Safran U.S., the "Sellers"),  the Registrant acquired (i) the
     Stock of  Cinch U.S. from Safran U.S. and (ii) the Stock of Cinch U.K. from
     Safran U.K., in exchange for an aggregate  purchase price of  approximately
     $37,500,000.00 in cash plus approximately  $1,500,000.00 for the assumption
     of certain expenses. The cash portion of the purchase price was funded with
     cash  on  hand.  The  final  purchase  price  remains  subject  to  certain
     adjustments  related  to  working  capital.  As part of the stock  purchase
     agreement, the Registrant also indirectly acquired, through its acquisition
     of Cinch U.S.,  approximately  99.9% of the issued and outstanding  capital
     stock of Cinch Connectors de Mexico, S.A. de C.V. ("Cinch MX" and, together
     with Cinch U.S. and Cinch U.K., the "Cinch Companies"),  which such capital
     stock is owned by Cinch U.S.  The other approximately  0.1% of Cinch MX was
     transferred from Labinal  Investments,  Inc., a wholly-owned  subsidiary of
     Safran  U.S.,  to Bel  Ventures  Inc.,  a  wholly-owned  subsidiary  of the
     Registrant.

          The Cinch Companies manufacture a broad range of interconnect products
     for customers in the military and  aerospace,  high-performance  computing,
     telecom/datacom, and transportation markets.

          The Registrant has issued a press release  describing the  acquisition
     of the Cinch Companies.
