Pulse Electronics Corp. said Tuesday that a competitor may try to nominate three candidates for the 2011 election of its board of directors.

Trevose-based Pulse had attempted to acquire Jersey City, N.J.-based Bel Fuse Inc. for $514 million in 2007, but was rebuffed. Pulse, an electronic components maker that changed its name from Technitrol Inc. as of Nov. 8, said that Bel Fuse had expressed interest recently in "restarting discussions about a potential business combination."

Pulse shares closed at $4.36, down 11 cents.    - Mike Armstrong
