The Great Search: LED and Dual-Touch Metal Dome Switches
This week's Great Search is on clicky dome switches! We saw a thread on X (https://twitter.com/RueNahcMohr/status/1716162430265602509) showing off the Snaptron (https://www.digikey.com/en/supplier-centers/snaptron) starter kit - you can pick up a sample box kit for free from (https://www.snaptron.com/free-samples/sample-box/) if you want to try these too.
We first saw these on the Pocket CHIP (https://shop.pocketchip.co/collections/frontpage/products/pocket-c-h-i-p-new) as a low cost way to create a key array. One new type we saw is the BL series (https://www.snaptron.com/products/standard-domes/bl-series/) which allows having an LED behind the dome - you'll need a reverse mount LED so it doesn't get crushed. And the DT series which allows two level of actuation (https://go.snaptron.com/DT-Series-White-Paper_V2.0).
