F4 switches are available with either silver or gold-plated silver contacts.
Switches with gold-plated contacts are intended for use in circuits where switching is at milliwatt levels.
In this case, the power being switched must be limited to avoid the erosion of gold plate from the contact area.
However, as the underlying contacts are silver, the same power ratings apply.
