Yellow's the colour that says 'press me' without a label. This Jaycar snap action switch mounts onto your PCB, stays open until you hit it, then closes for exactly as long as your finger is down. 5mm pin spacing fits standard pads and breadboard rows. Contact rating is 10mA / 35V DC – right in the sweet spot for signal-level control on a keyboard, access panel, or hobby project. No extra relay needed. Solder it in, test the click, move on to the next part
