Basis of Presentation [Abstract]
Basis of Presentation	The accompanying condensed consolidated financial statements have been prepared by CTS Corporation (“CTS” or “the Company”), without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements should be read in conjunction with the financial statements, notes thereto, and other information included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The accompanying unaudited condensed consolidated financial statements reflect, in the opinion of management, all adjustments (consisting of normal recurring items) necessary for a fair statement, in all material respects, of the financial position and results of operations for the periods presented. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ materially from those estimates. The results of operations for the interim periods are not necessarily indicative of the results for the entire year.
Presentation of Financial Statements - Liquidation Basis of Accounting	ASU 2013-07, “Presentation of Financial Statements – Liquidation Basis of Accounting” In April 2013, the FASB issued Accounting Standards Update 2013-07, “Presentation of Financial Statements – Liquidation Basis of Accounting,” which contains guidance on applying the liquidation basis of accounting and the related disclosure requirements. Under the ASU, an entity must use the liquidation basis of accounting to present its financial statements when it determines that liquidation is imminent, unless the liquidation is the same as that under the plan specified in an entity’s governing documents created at its inception. Liquidation is imminent when the likelihood is remote that the entity will return from liquidation and either (a) a plan for liquidation is approved by the person or persons with the authority to make such a plan effective or (b) a plan for liquidation is being imposed by other forces. The amendments require financial statements prepared using the liquidation basis of accounting to present relevant information about an entity’s expected resources in liquidation by measuring and presenting assets at the amount of the expected cash proceeds from liquidation. These amendments are effective for entities that determine liquidation is imminent during annual reporting periods beginning after December 15, 2013, and interim reporting periods therein. Entities should apply the requirements prospectively from the day that liquidation becomes imminent. The provisions of ASU 2013-07 are not expected to have a material impact on CTS’ consolidated financial statements.
Derivatives and Hedging	ASU 2013-10, “Derivatives and Hedging – Inclusion of the Fed Funds Effective Swap Rate as a Benchmark Interest Rate for Hedge Accounting Purposes” In July 2013, the FASB issued Accounting Standards Update 2013-10, “Derivatives and Hedging – Inclusion of the Fed Funds Effective Swap Rate as a Benchmark Interest Rate for Hedge Accounting Purposes,” which permit the Fed Funds Effective Swap Rate (Overnight Interest Swap Rate) to be used as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to UST and LIBOR. The amendments also remove the restriction on using different benchmark rates for similar hedges. These amendments are effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The Company does not expect these provisions to have a material impact on CTS’ financial statements.

Disclosure of accounting policy for reporting when there is a substantial doubt about an entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date). Disclose: (a) pertinent conditions and events giving rise to the assessment of substantial doubt about the entity's ability to continue as a going concern for a reasonable period of time, (b) the possible effects of such conditions and events, (c) management's evaluation of the significance of those conditions and events and any mitigating factors, (d) possible discontinuance of operations, (e) management's plans (including relevant prospective financial information), and (f) information about the recoverability or classification of recorded asset amounts or the amounts or classification of liabilities. If management's plans alleviate the substantial doubt about the entity's ability to continue as a going concern, disclosure of the principal conditions and events that initially raised the substantial doubt about the entity's ability to continue as a going concern would be expected to be considered. Disclose whether operations for the current or prior years generated sufficient cash to cover current obligations, whether waivers were obtained from creditors relating to the company's default under the provisions of debt agreements and possible effects of such conditions and events, such as: whether there is a possible need to obtain additional financing (debt or equity) or to liquidate certain holdings to offset future cash flow deficiencies. Disclose appropriate parent company information when parent is dependent upon remittances from subsidiaries to satisfy its obligations.
