Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In October 2015, subsequent to fiscal 2015 year end, $30.0 million of an accordion feature under the Credit Facility was exercised, increasing the maximum commitment under the Credit Facility to $265.0 million. The Credit Facility may potentially be increased to $335.0 million, generally by mutual agreement of the Company and the lenders, subject to certain customary conditions. On November 4, 2015, Plexus announced plans to close its manufacturing facility in Fremont, California (“Fremont”) as a result of the Company’s optimization of its capacity to align with customer demand due to changing end-market dynamics. This action was approved by Company management on November 3, 2015. Plexus expects to incur approximately $3.0 to $5.0 million of restructuring charges as a result of this action by the end of the third quarter of fiscal 2016, comprised of employee, transition and other facility-related costs. The restructuring charges remain subject to additional analysis. The closure of the Fremont facility will affect approximately 200 employees. It is anticipated that existing customer programs at the Fremont facility will be transferred to other Plexus facilities. Plexus currently expects that the consolidation efforts related to this action will be complete by the end of the third quarter of fiscal 2016.
