Termination of Registration Statement and Deregistration of Securities

     CTS Corporation (the “Company”) previously filed a shelf registration statement on Form S-3 (Registration No. 333-117826) (the “Registration Statement”) with the Securities and Exchange Commission (the “Commission”) on July 30, 2004, which the Commission declared effective on August 20, 2004.

     The Registration Statement registered resales of up to $60,000,000 in aggregate principal amount of the Company’s 2.125% Convertible Senior Subordinated Notes due 2024 (the “Convertible Notes”) as well as up to 4,000,000 shares of the Company’s common stock (the “Common Shares”) issuable upon conversion of the Convertible Notes. The Company was contractually obligated to register resales of the Convertible Notes and Common Shares and to maintain the Registration Statement’s effectiveness for a specified period of time. The Company is no longer contractually obligated to maintain the effectiveness of the Registration Statement due to the expiration of such period. Accordingly, this Post-Effective Amendment No. 1 is being filed in order to deregister $60,000,000 in aggregate principal amount of the Convertible Notes and 4,000,000 Common Shares.
