Item 5.02 Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers.

(a), (b), (c) Not applicable.

(d) The Board of Directors of Plexus Corp. has appointed Michael V. Schrock as a new member of the Plexus Board of Directors, effective immediately. The press release announcing that appointment is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

Determinations have not yet been made as to Mr. Schrock's committee assignments. Pentair and Plexus purchase small amounts of products and services from each other; in 2005, the annual amounts of those purchases were below 0.2% of either Plexus' or Pentair's net sales. Therefore, Nasdaq stock market rules permit the Plexus board to determine that Mr. Schrock is an "independent" director, and the Plexus board has made that determination.

Item 9.01 Financial Statements and Exhibits.

(c) Exhibit 99.1 Press Release
