    Making an emergency stop switch for my Apex... push this and essentially all equipment will stop. There are several pre-made super cheap options on eBay but I wanted a low profile large aluminum switch.
    ** If you don't have an Apex but still like the idea of an master emergency switch post below for help.

    Are there any pieces of equipment you wouldn't want shut off in an emergency? I'm thinking lights because they plug into a outlet above the system and not exposed to water that may drip. Dunno.

    I still need to cut the box down ~40% thinner.

    Sticker "designed" and ordered... channeling my inner Apollo 13!

    it depends on the emergency you plan on reacting to.

    water on the floor? light can stay on

    lights on fire? probably want to cut power to the lights.

    any emergency? EVERYTHING off

    I will have a several extra stickers if anyone is wanting a similar box made. Happy to do so at cost if it's not going to sit on a shelf.

    Probably any equipment then as it's meant to be a true emergency.

    I had to google that... there is a highly disproportionate number of IT related people on this forum :D

    I believe the answer is "yes" at this point nearly everything is run through the Apex and this particular switch is low voltage. It could of course be easily swapped out for a higher amp version for anyone not using an Apex or similar.

    If that switch is a SPDR with a wall wort and one or two of the supplied pic you can have it shut off your 110v non-apple equipment as well.

    If that is something you would like I can help you more in detail. [​IMG]

    I actually just got that exact switch in the mail to control my Ehiem feeders remotely. My particular emergency switch is not powered, just a press and hold to create a break long enough for the Apex to register. However, I see where you are going with it and I like it!

    That would make for an easy Master Emergency switch for any system Apex or not, great idea!

    *** Edit *** Actually wouldn't need a fancy powered switch would I, just a simple 12v power supply and a switch that holds it's position (click on / click off).

    I ordered a 4 button, 2 switch box off another forum that plugs into the i/o apex port. works great. I have one button for water change, one to make new RO water, one to turn on extra overhead lights and one to turn on my NSW light so i can see the water level. One switch controls my NSW mix pump and the other shuts everything off. LOVE IT!

    Stickers arrived today! Now if I can only figure out where I put the switch...

    Got matte and gloss since I could double the order for $2.00

    The lighter orange spots was put in in hopes of looking a bit like a backlight. The big circle will of course be covered by the switch.
