PART FINDER FRIDAY – Judco SPST. A maker in the forums was looking for a ‘alternating action switch’ – one that acts like a button but is on or off. These are familiar to people with old PC’s or game consoles, that big button in front that would shut the whole machine down. Problem is most of the time the buttons are huge and he wanted a smaller one. We had the same desire when we make the Wave Bubble, and the part we found then is probably the best thing out there: a Judco SPST (there is also an SPDT version). These are good for 300mA @ 12V which makes them a nice clicky power button for your projects! Of course, its also in the adafruit Eagle library.
