Symbol + footprint reconstructed from manvalan/DigiRadio's EasyEDA
project (same method as the FSC-BT1035 footprint), cross-checked
against the manufacturer datasheet found in that same project. The
datasheet's own circuit diagram shows two independent, mechanically
-ganged contact pairs (not a simple SPST), reproduced faithfully in
the symbol. Pin numbering preserved exactly as extracted, kept
internally consistent between symbol and footprint.
