Hello to all,
How is the rating of a relay converted to RF usage?

A company normally gives the voltage and current  rating for the relay
contacts:

250 v ac @ 2 amps  (assumed at 60 CPS)
30 v dc @ 3 amps

Also in some cases the maximum voltage from contacts to relay coil.

How would this example rate for RF usage up to 30 MHz?

What is the formula to be applied to other relays?

What is the formula to be used for power in watts?

Will there be an impedance bump at the relay?

If there is an impedance bump should it be considered a problem ?

Should SWR in the line be a consideration?

Thanks
