Hey,

I've long had my setup with a master power switch between the car battery and the opus. It's on the load-bearing 12v positive line so I can do a hard reboot whenever the computer locks up.

Well, last night the switch died. I think I may have been drawing too much power through it. It was always very warm to the touch, but I never did anything about it because it did the job. Now that it's officially dead, I am looking to replace it with a switch that would be better suited. My plan is just to walk into the local radioshack and ask for a switch, but I dont want to end up with another puny lil guy that will just overheat and break eventually as well.

What should I be looking for? How many amps would my Opus 150 draw? Is that the critical number I need to consider? The switch is largely behind-the-scenes, so aesthetics aren't that important.

Thanks for any help.

Get a standard automobile relay and use any switch to control the relay.
A relay can handle much more current than a switch.

Forget the electronics shop.

Look at automotive switches. They are built for 12v (automotive circuits) and even the 'light' versions can easily handle 5 to 10 amps. Heavy duty switches can easily do up to 30amps. Probably overkill but the price difference is like a couple dollars.

The added bonus is that they blend in very well and look OEM should you decide to mount them in your dash.

Okay, so not radioshack. Autozone?

Walk in and ask for a load-bearing 12v switch. Gotcha.

Thanks!
