Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

1 DIY

Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

  • Does anyone know what type of connector I need for this switch. I need to solder a wire to a connector that slides onto each terminal post.

    • Yes, it would be nice if the terminal width was listed in the description.

      • I found this post on the comments on this connector :

        "FYI: I happen to have some of the Sparkfun arcade buttons (both kinds). I measured the terminals on both (with calipers), and here are the results: “Concave Button” (COM-09336): 0.187 inches – will work with 1/5" (0.2", a little big, but close enough) “Push Button” (COM-09177): 0.110 inches – way too small for 0.2" quick disconnects"

  • I wrote a quick how-to to show how to install an LED into these to illuminate them see http://www.instructables.com/id/HackMod-a-concave-arcade-style-button/

    • Awesome. Thanks. I also followed your instructions and placed an RGB LED inside. I recommend using reflective aluminum duct tape or silver paint inside the button walls to make it glow brighter, or use a clear LED. The diffused ones make the whole thing glow with not much spotlight effect, but it is a bit dim.

      Reflective tape:

    • I put a RGB (clear) in like you mentioned could be done on your instructable. Feel free to link this there if you want.

  • This probably sounds like a really obvious question, but I have to be sure: If one were designing an enclosure for these in a CAD program, would one make the holes 28mm and assume the button will fit perfectly?

  • What do you guuys use to bore the mounting hole?

    • Something like this would be best IMO.

      • The (2 year old) link is dead. Do you have another link, or a generic name for the part/process you were recommending?

        • hum, no idea. It was probably just a hole-saw. something like this. the material depends though. if going into wood, plastic, etc, a hole saw should be fine. if thin metal, a punch is better.

  • While these guys are a bit more expensive then the 33mm convex ones sold here, they're actually a pretty good deal when you consider the fact that the microswitch included with them is over 3/4 the price. You're only paying $0.45 more for the nifty arcade button.

  • Are these switches momentary switches, or, um, what's the word... do they stay "on" until you click 'em again?

    • Trying to be nice about the post, but as the description suggests. They are momentary switches. I apologize if this was not in the description when you posted this comment.
