This is a variactor diode.

That is a diode with a capacitor bypassing it.

that symbol is an open contact in the control world.

  Oh my, I didn't think anyone else here ever dabbled in Relay Ladder Logic.
  They are not still using RLL for PLC's are they? I would hope they moved on to something a little more powerful like LabView.
  But you are correct that symbol is a normally open relay contact in RLL and a nonpolerized capacitor in schematics.

    in the world of power distribution and control, or the world of "big electrons" as one of my coworkers used to say, power contacts and even little bitty control relay contacts are shown like that symbol in schematics and catalog literature.
