    Brass button

    Been searching high and for brass momentary switches with little luck.

    Best I have found so far was this one that was meant to be be chrome plated brass. I thought I could just sand back the chrome to reveal the brass. I stared sanding the actual button on one of them and it wasn't doing anything but scratching it. I'm guessing the button is SS. I sanded back the surround and it looked like copper to start but it looks like there may be some brass under the copper layer.

    I've got no idea how plating works. Perhaps there is a layer of copper between the brass and chrome.

    Anyway..... Any idea of a source for brass buttons?

    No idea on a source ... but as far as chrome plating goes ... read on.

    Chrome plating is mostly applied to nickel plating, which itself is applied over a copper plating, which is applied over the base metal. This is commonly called "triple chrome".

    The copper plating is used to cover up blemishes in the base, where as the nickel is used due to it's ability to bind to both the previous coating and the last coating.

    Triple chroming is the best quality.

    Cheers for that, GT. I'll keep sanding....... and seaching for brass buttons!

    Do you have any idea how much current the switch will have to carry?

    No idea - 18650 battery and a Vamo board. Not sure what other info you need to work out that. My grasp on electronics is very much in it's infancy.

    Thanks for looking but not really after gold. The site doesn't tell me what the base metal is.
    I've found lots of these with brass bodies but the ball head always seems to be stainless.

    We should ask Robray, his switch is off board now, he could stick a multimeter in series and measure the current.

    if you're using a Vamo board (or most other boards for that matter) the switch isn't going to be carrying much in the way of current, it's just a trigger for the electronics so no need for something like a 5A switch think you'll find 250-500mA is fine. That said I like big switches for both durability and looks and using a high rated switch wont hurt anything.
    Hope that makes sense and is of some help
    cheers

    Just seen this.

    All I have done is to replace the original tac switch with a big un. I am guessing that the rating of the original cant be more that 100ma. Cant measure it just yet, cos its still a work in progress. (Thanks to the wife!)
