It's not a normal symbol, it may perhaps be supposedly a switch?.
But the entire circuit looks weird!.
Perhaps it is meant to be a test point?
Fine,
You have shown us a schematic as you got it. why not take a real photo of the portion of circuit?
I presume it to be ferrite bead for RF Higher frequencies or Harmonics not to interfere with the working.
As rightly pointed by Nigel, the circuit appears weird. I imagine that the designer is extracting multiple outputs from one input and at different impedances, as already indicated by you.
