Switch In Line With CB Power?
Post by dancrosoft »
I would like to put a kill switch inline with my Galaxy DX98VHP. I have 8 Gauge wire ran to the battery - 50amp fuses at battery and at radio. I would like to install a switch inline so I can kill the power. Can anyone comment on if this is a bad idea or not? It seems quite hard to find a quality 12VDC toggle switch rated at 50AMPs but they are out there. In addition (I am no wiring expert) but from what I understand the wear and tear on switched is due to arc when being flipped under load. If I turn the radio off then flip the switch - would that negate said wear and tear?
Another option would be a relay but I haven't thought that one out in my head yet I hate adding complexity when its not needed.
Thanks for any advice!

They do make then, here is one, just "Google" kill switch",
There shouldn't be any arching if the radio is turned off and it's not a good thing to turn on the kill switch with the radio on. Some radios do draw current when in the off position but I don't think that is one. Personally I don't think it's necessary.

You could use a relay triggered by an accessory connection in the fuse box. That way the radio only has power when the key is on. The 95t I have runs the fans at certain temps if the radio is on or off. They draw very little current. All the time I had it mobile I never had a dead battery because of it.

An easy switch could be two 30A relays in parallel. A common 12V switch could fire it on or off. Why do you need a Kill Switch on the Radio? 543 makes a good point about some radios with fans running with the radio and truck turned off due to the sun heating up the cabin. I have a 2970N2 with the same type of fan. Even in Louisiana I dont have a battery issue when I dont use my truck. It might even be a month or two during the heat of the summer before I use it and I never have any battery draw issues. I also have two batteries so this might make a difference as well.

Thanks for all the help. I went without the switch on this one for now . May put it back in when I get the other issues resolved.
