Normally the power switch on a Corsair is not even connected to the 12 volt
leads, so you could turn the switch on and off all day and it won't do a
thing unless it is connected to a Ten-Tec supply. In fact the 4 wire Ten-Tec
supplies won't even turn on unless it is connected to the radio or the two
center pins or wires are jumpered because the switch in the rig completed
the circuit. Sounds like your rig has been modded to switch the power from
the front panel. Maybe the switch he put in is heavy enough to carry the
current load. As Mike said, the original switch was meant to handle only the
low amperage AC current.
In my mind and from what I have learned from listening to discussions on
this reflector is it is safer to switch the power from the Airpax breaker
AFTER the supply has been turned on and the voltage is stabilized. And as
you said, you don't want switch the supply off and have the lingering
voltages as the supply discharges. The breaker is instant on and off.
I have not owned any of the later Ten-Tec rigs thus far ( Anyone have a
Jupiter for sale? ) so I can't speak for the Omni V, but I believe the
switch in those is able to handle the DC current. Someone else will need to
answer that one for sure.

Ed, why can't you use the front switch to turn the rig on and off?
I have a Corsair II on an Astron power supply I use the outside pins of the
plug from the radio that goes to the power supply.
I have an Airpax in line with the power supply.
I turn on the power supply with the power supply switch.
The Airpax is always on and I turn the switch on the Corsair II to turn the
rig on.
I have never had a problem.
Am I doing something wrong?
My rigs on off switch was replaced by the first owner with one that clicks
on
and then turns for volume.
Seems TT does not sell the pull out ones anymore.
He told me he did a mode when he replaced the switch that would also let me
turn on the power supply form the radio safely.
Have you heard of that?
Let me know about this.
It has always puzzled me.
I have an Omni V and was told to always turn that radio off from the radio
and not to let it turn off by leaving it on and turning off the power
supply off.
I was told the slow decay turnoff would harm the radio.
Can I turn off the Omni V with the Airpax?
Any thoughts?
