                 Re:          Registration Statement on Form S-3
                              ----------------------------------


Ladies  and  Gentlemen:
     We  have  acted  as  counsel  to  Orbit  International  Corp.,  a  Delaware
corporation  (the  "Company"),  in connection with its Registration Statement on
Form  S-3 (the "Registration Statement"), filed with the Securities and Exchange
Commission  on  December  22,  2005,  with respect to the registration under the
Securities  Act  of  1933,  as  amended (the "Securities Act"), of the resale of
206,129  shares  of  common  stock  of  the Company (the "Shares"), which may be
offered  and  sold  by  certain  selling  shareholders  of  the  Company.
     This opinion is being delivered in accordance with the requirements of Item
601(b)(5)  of  Regulation  S-B.
     We  have  examined originals or certified copies of such corporate records,
certificates of officers of the Company and/or public officials as the basis for
the  opinions  set  forth  below.  In  such  examination,  we  have  assumed the
genuineness of all signatures, the authenticity of all documents submitted to us
as originals, the conformity to original documents of all documents submitted to
us  as  conformed or photostatic copies and the authenticity of the originals of
such  copies.
     Based upon our foregoing examination, subject to the assumptions stated
above and relying on the statements of fact contained in the documents that we
have examined, we are of the opinion that the Shares issued and outstanding as
of the date hereof are duly authorized, legally issued, fully paid and
non-assessable.
     We  are  qualified  to  practice  law  only  in  the  States  of  New York,
Connecticut  and  Massachusetts.  We  are  not  qualified and do not express any
opinion herein as to the laws of any other jurisdiction, except the federal laws
of  the  United States and, to the extent required by the foregoing opinion, the
Delaware  General  Corporation  Law. Otherwise, to the extent this opinion deals
with  matters  governed  by or relating to the laws of any other states, we have
assumed  that  such  laws  are identical to the internal substantive laws of the
State  of  New  York.
We  hereby  consent to the filing of this opinion as an exhibit to the Company's
Registration  Statement  on  Form  S-3 and to the use our name under the heading
"Legal  Matters"  in the Registration Statement, including the prospectus or any
supplement  to  the prospectus, constituting a part thereof, as originally filed
or  subsequently  amended.  In giving this consent, we do not thereby admit that
we  are within the category of persons whose consent is required under Section 7
of  the  Securities  Act,  or  the  rules  and regulations of the Securities and
Exchange  Commission.
     Very truly yours,

      Robinson & Cole LLP
