Exhibit 31.2
   (1)
    
    I have reviewed this quarterly report on Form 10-Q of Technical Communications Corporation;
 (2)
    
    Based on my knowledge, this report does not contain any untrue statement of a material fact
or omit to state a material fact necessary to make the statements made, in light of the
circumstances under which such statements were made, not misleading with respect to the period
covered by this report;
 (3)
    
    Based on my knowledge, the financial statements, and other financial information included in
this report, fairly present in all material respects the financial condition, results of
operations and cash flows of the registrant as of, and for, the periods presented
in this report;
 (4)
    
    The registrants other certifying officer and I are responsible for establishing
and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e)
and 15d-15(e)) and internal control over financial reporting (as
defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:
 a.
    
    designed such disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under our supervision, to ensure that material information relating
to the registrant, including its consolidated subsidiaries, is made known to us by
others within those entities, particularly during the period in which this report is being
prepared;
 b.
    
    designed such internal
control over financial reporting, or caused such internal control
over financial reporting to be designed under our supervision, to
provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles;
 c.
    
    evaluated the effectiveness
of the registrants disclosure controls and procedures
and presented in this report our conclusions about the effectiveness of the disclosure
controls and procedures, as of the end of the period covered by this report based on such
evaluation; and
 d.
    
    disclosed in this report any change
in the registrants internal control over
financial reporting that occurred during the registrants most recent fiscal
quarter (the registrants fourth fiscal quarter in the case of an annual report)
that has materially affected, or is reasonably likely to materially affect, the registrants
internal control over financial reporting; and
 (6)
    
    The registrants other certifying officer and I have
disclosed, based on our most recent evaluation of internal control over financial reporting, to the registrants
auditors and the audit committee of the registrants board of directors (or persons
performing the equivalent functions):
 a.
    
    all significant deficiencies and material weaknesses in the design or operation of internal
control over financial reporting which are reasonably likely to adversely affect the registrants
ability to record, process, summarize and report financial information; and
 b.
    
    any fraud, whether or not material, that involves management or other employees who have a
significant role in the registrants internal control over financial reporting.
