CORALVILLE, Iowa (AP) _ Electrical workers at a Rockwell Collins plant Friday approved a five-year labor agreement, ending a 16-day walkout. Fellow union workers at a Rockwell plant in California remained on strike.

Local 1634 of the International Brotherhood of Electrical Workers, which represents about 700 workers in Coralville, agreed to return to work on Sunday.

Terms of the contract were not released. But union officials have said that workers wanted better pay and benefits, including retention of their current medical plan and eye care coverage.

Union officials could not immediately be reached for comment.

Jack Cosgrove, president of Costa Mesa, Calif.-based Rockwell Collins, said in a statement that he was pleased the contract had been approved and he thought it addressed the needs of the union.

The Coralville plant makes government guidance and radar systems.

Union workers remain on strike at the Rockwell Semiconductor Systems business in Newport Beach, Calif., but operations continue while both sides arrange for talks. The union represents 630 workers.

Rockwell Semiconductor Systems and Rockwell Collins are both subsidiaries of Rockwell International Corp.

Rockwell International employs about 48,000 people worldwide in operations that include industrial automation, avionics and communications.
