A sortation conveyor for transporting and diverting a plurality of articles includes a first conveying path and a second conveying path angularly positioned relative to the first conveying path. A plurality of pusher elements may be selectively diverted laterally across the first conveying path to divert articles to the second conveying path. A piezoelectric actuated switch assembly positioned adjacent to the second conveying path selectively engages the pusher elements to divert the selected article to the second conveying path.
