I still have a few hundreds of low power ( Clare PS1201 ) and a few
RC4425-D12 ( 440v~ 25 Amps 4-32V DC )Projected to use the LP PS1201 )
as AC switches in my Yeasu G-2000RC command box as I have to repair it
anyway. The big ones should be used on a Amp HV PS .......reading all
this comments, I just wonder if it?s a good idea......It just bothers me
that no one talked about snubber circuits!
Just a few hours back from Hospital and a surgery I can't concentrate,
but there is some stuff when I do a google on snubber.
Unfortunately I can only listen with one ear....
What say gentlement?

Winding resistance is one factor. There is also the capacitance of
the filter caps and the inductance of both primary and secondary of
the transformer.
A zero-crossing circuit which works well with one
transformer/capacitor combination might not be satisfactory with
another.
