Default Need help from the Eletrical/Electonics experts!

I would like to use DC switches on my control panel to use as master switches for my elements and my pump.

I am not set on DC what I am set on is the ability to use normal sized toggle switches.

I want the ability to turn the 120v power off on one element. The 240v power on the other element and a switch to turn the pump on/off. My PID and and thermometers are running on a 12v circuit so I will have a master switch for the 12v bus as well.

I have found 120v toggle switches that could do the job I think but they are ugly standard toggle switches. 12v switches seem to have more of a bling factor that will fit into my design.

I've always liked bigass Frankenstein-style knife switches, but that's a personal thing.

Can't you just run the DC switch to the control side of a relay and call it a day?

Ok sorry to reply to my own post but I just found this. Rocker Switch

I can work with this. How could I use one of these to switch the 240v. I have a 5500w element. I am not sure how to switch a device with that much current.

That was what I was thinking but I am lost trying to find the right relay. I would rather not spend $20/each for solid state relays. The switch will only get turned on and off a few times during a brew, so longevity is not a concern.

I need a point in the right direction for a standard non-SSR relay.

I recommend you go with either 24v DC or 120v AC for the control panel. Personally, I went with 120v AC for the control panel to avoid installing a bunch of relays for the pump, mill, water solenoids, etc. Everything is water tight and GFI covered, so no worries.

However, I do use a 24v DC supply for the electric float switches that sit in the HLT and MLT.

Have a look at the Automation Direct lighted switches. They sell industrial quality, configurable LED switches for a reasonable price.

I have 12v DC to power my PWM and my Thermometers. My PID takes the 12v input too. So I already have that source available. I am hoping to keep 120v out of the panel and isolated to the water tight electrical enclosure I have for the SSR's and main bus for the elements.

$15+ for a switch is pricey. Toggle switches are a few bucks. Relays should only be a few dollars too.

I may end up going that route. I just don't really want bulky switches and 120v in my panel if I can get around it.

Sometimes, you pay for what you get...These ain't cheap "Radio Shack" switches.

True; but an industrial rated toggle is still only $3

You're not going to have much luck finding a 240v, 30a, DPST relay with a 12v coil for a few dollars.

Ok I found these. http://www.factorymation.com/s.nl?it=A&id=518&whence=

If I can not make this work I guess I will have to go with 120v in my panel. This is a bit better then $15 per switch. Total would be $7.50 per switch

NEVER MIND:

Those switches can not handle the amps. I suppose that is why they are so cheap. Back to the drawing board.
