Hey there DIYers and electronics folks! These Aexit round rocker switches are exactly what you need for your projects. You get 5 switches in the pack, which is perfect for having spares. They've got that cool red light that lets you know when they're on, and the black/green color combo looks pretty sharp. Now, here's the important stuff - they're SPST (single pole single throw) with 3 pins, and rated for AC 250V/6A or 125V/10A for resistive loads. But pay attention - the ratings change for different types of loads! For inductive loads it's 2.1A at 250V, lamp loads 1.08A, motor loads 1.2A, and capacitive loads 1.08A. At 125V you get a bit more amperage. Oh, and if you're using DC, keep it under 0.5A or check with the manufacturer first. The mounting diameter is 19mm (about 0.7 inches), and overall they measure 22x27mm. They feel solid with plastic and metal construction, and at 27g each they've got some heft to them. Whether you're building a custom panel, fixing appliances, or creating something new, these switches handle the job. The model is KCD1 if you need to look up specs. Just make sure you match the ratings to your specific application - better safe than sorry with electrical components! Having five means you can mess one up and still have plenty left, which is always nice when you're learning or experimenting.
