I’m currently working on an idea for a very small device (approx 2mm^3). The goal is to make something that would go between something like a keyboard and the rubber padding that makes contact with the keyboard’s motherboard. The purpose of the device is to “quick click” a button on the keyboard. In other words, it will click and unclick the button no matter how long the button is held. So once the button is pressed, the device will automatically retract and even if the button is still held the device will have unclicked and won’t click again until the next time the button is pressed. Ideally, the device will execute this incredibly fast and the button won’t make contact for longer than 1/30 of a second.
I’ve been working with different designs that resemble a pen’s mechanism but can’t think of a way to implement it in such a way that it retracts even when it’s held.
Long story short, I’m at a standstill and any ideas would be greatly appreciated!
