    In discussing troubleshooting on another post I made, I mentioned using a number of circuit breakers I had on hand, then got a couple of PMs asking about them, so....

    Ever burn through a 5-pack of fuses all too quickly while chasing down a trouble spot? Ever burn your last one after the local stores are closed? Ever go to the store only to discover the size you need is apparently the one oddball they do not carry or is out of stock (of course!)? Ever suffer the first-world anguish of a game down for days while you wait for "just a fuse" to be shipped?

    Yeah, it sucks. And this, incidentally, is how games get overfused with whatever is on hand, which is even worse!

    So stop it because circuit breakers are amazing! For just a buck or two more than a 5-pack of fuses you can plow through in a hurry, you can get an infinitely re-usable breaker that will keep you from literally burning that money the next time something goes wiggedy whack wrong.

    Mouser has a whole range of them:

    FS=True">http://www.mouser.com/TE-Connectivity/Circuit-Protection/Circuit-Breakers-Accessories/Circuit-Breakers/_/N-axfui?P=1yzs6ii&Keyword=circuit+breaker&FS=True

    Simply search for the amperage you need, and choose a push-to-reset model. Here are the common sizes I have found handy:

    2A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-2

    2.5A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-2.5

    3A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-3/

    4A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-4/

    5A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-5/

    7A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-7/

    8A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-8/

    10A: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/W58-XB1A4A-10/

    There are lots of other sizes available....

    To use them you need to save your blown fuses. Solder the breaker lugs to a bad fuse. The simply insert the fuse breaker as required, and troubleshoot away. (I will post a photo of mine later on).

    The first time you reset one three times, it will have paid for itself in spared fuses, saved time and fuel, convenience, and peace of mind. The assortment of breakers I listed above cost me maybe $40 and has been one of the most valuable bits of kit in my toolbox.

    Awesome! Thanks for the links.

    #3 2 years ago

    I made a set like 1.5 years ago. Came in really handy troubleshooting a sys 7 issue that was burning through fuses. Very handy maintenance tool to have on hand.

    One thing Ive found is the circuit breakers takes a little bit more to trip than a corresponding fuse. I would try to use a slightly lower amp rating (let's say a 10 amp circuit breaker for a 12 amp fuse)

    That little device has been around for years. Nice of you to post as it looks like quite a few people were not hip to it, and now more will be!

    #11 2 years ago

    I little pricey. You can also look in other places to save $:

    I actually saved some $ by ordering these types of breakers on e-bay. Search under "boating breaker" or "boat breaker" and not fuse or relay.
    It pays to look for these items through non-pinball sellers.
    I ordered like 20 different values for $2 each from a few different eBay sellers. FREE shipping too.
    These breaker fuse relays are also used in small planes. known as "avionic breakers" or "thermal breakers"...
    I found most of them from eBay sellers with lots of boating supplies.
    I once found some AIRPAX avionic breakers for like $1 each on eBay. They were military grade, out of an old fighter jet from the 70's that someone was parting out. Built so well that you could accidentally run them over with your vehicle and they will still funtion.

    #12 2 years ago

    Aww damn, I need to get me some fighter jet breakers now

    I'm sure most folks figured it out, but as promised here's a photo of the fuses soldered to the breakers.

    I saw that pic and thought those were mine for a min. I did the same thing exactly with the rating done with white paint pen on the side and soldered bad fuses to them. Exactly.

    #14 2 years ago

    Please forgive my ignorance here but how do we know if the breakers are fast blow or slow blow?

    #15 2 years ago

    The button pops out.

    This is great advice. They trip slower and can cause problems; we burned a ground trace once with one of these it took so long to pop.

    #17 2 years ago

    ALWAYS use 1 amp less than required when using these! They absolutely take longer to blow than a comparable fuse. If using in a fast blow application I would use even 2 amp less. better to have to hit the switch than repair the board.
    Also solder alligator clips with lead wires instead of blown fuses then it is good for all fuse types and sizes. Been using mine for many years on all generations of boardsets ... LOVE them.

    #18 2 years ago

    Could have saved you some time. Just did the same post last month. They work great.
    https://pinside.com/pinball/forum/topic/push-button-resetting-circuit-breakers

    hawk007 That is what I recommend also. Use either 1amp less or 1/2 amp less. They are all slow blow.

    Heh... silver sharpie, white paint, it's all the same... I'm glad to be in good company

    That's not a bad idea in concept... come to think of it, I don't think I've ever yet used these in a fast-blow application to where I would have paused to consider it. But then how often would being too low a rating cause it to blow when the circuit is otherwise fine, just running within the higher (normal) spec? Would hate to end up chasing "false positives" because a too-low fuse keeps blowing. OTOH maybe that's better than something else getting damaged...

    #21 2 years ago

    You boys and your breakers. I made one of these, good for up to 5A

    You mean all those people that kept telling me over the years repeatedly to use a piece of rolled up piece of tin foil for testing were wrong?

    #23 2 years ago

    I saw Clay use these years ago, I assume he's the first? Or did he pick it up from someone else?

    tin foil? Novice. everyone knows you are suppose to use full metal jackets.

    #27 2 years ago

    I picked up a few of these a while back from Ed at Great Plains. I haven't used them yet - but I am glad to see the pics and info about soldering a fuse and other tips on amps, etc.

    #28 2 years ago

    do not solder a fuse to it. Use alligator clips with lead wires so it works on all types and sizes of fuses in any location. see my earlier post.
    Cheers!

    #29 2 years ago

    When I made mine I had soldered fuses to my set... a lot easier than fumbling with alligator clips, but good point about the different size fuses. Fortunately this works for 99% of what I typically work on.

    Now that you mention it though might go ahead and make another set with clips though just so I'm not caught with my pants down.

    Was this originally a Bob Roberts tip? I remember having had read it somewhere once upon a time.

    #30 2 years ago

    I have some of these made up.
    I used a 3 amp one in a 5 amp location when troubleshooting a pop bumper on my BK2000.
    Ended up burning out the coil.....didn't pop nearly as early as it should have.
    Not sure they are great for every condition like this.

    Thanks

    Only on re-imports from Europe. Then you have to use a #8-14.

    I contacted the designer, and he still has boards available. his email is sjnewt@att.net

    that's pretty cool, but only goes up to 5A. Which really limits it's use. if they had one that went up to 20A that would be awesome.

    I contacted the designer about possibly designing one that has a higher amperage range. This is good for the smaller amp(5 and below) situations. Any suggestion on the range for fuses?

    for pinball you use 3/8 A up to 20A

    Just solder 2 full metal jackets together...

    Most of my stuff only goes up to 10 amps. I would think you would be more worried about the maximum wattage. If it could handle up to 400 watts, that would be pretty good. If blank boards were made available, I would buy one in a heart beat.

    #42 2 years ago

    Ok, we have a lot of EE types here.... How about a Pinside Group Project!!

    I've heard some pretty cool requirements:
    Variable range covering from - 3/8A thru 20A
    400 Watt upper end
    Digital readout
    Is there a way to simulate "fast blow" as opposed to "slow blow" or per Hawk007's comment, is it enough to just dial back the rating. (not a EE... sorry if that's a stupid question).

    Can we extend the original plans to increase capability?
    I'd really like to build this myself... this looks like a fun project.

    #43 2 years ago

    hey faz, great idea.
    We could use it all the way down to 1/4 amp or even 1/16 of an amp for testing hv circuits.

    The docs in the download mentions it can be upgraded to support 20 amps. A few parts need to be changed, but you'll need to contact the author to get an updated micro code:
