Cool Components VIII: Make Your Own Metal Buttons
At the Design West 2012 / Embedded Systems Conference I had the opportunity to try out a unique technology: Microchip Technology’s mTouch metal over cap buttons.Â This technology provides the capability to fairly easily create affordable custom non-contact metal buttons.
Since this technology uses capacitive sensing, the buttons are non-contact and should have a long life.Â However, they’re still very short stroke and thus provide very little mechanical feedback.Â Microchip’s demo used LED point lights to provide feedback.Â Microchip’s demo kit currently isn’t available for sale, but they said it was coming sometime, probably for less than $100.
You could use this technology to make ESD-safe buttons.Â However, since the metal needs to bend a bit, it won’t be as rugged as the more expensive anti-vandal buttons.
I’ll probably buy the demo kit when it comes out, because it’s a cool gadget…
