Detector Switch vs Micro Switch: What’s the Difference? When a product fails in the field, engineers often investigate firmware bugs, PCB defects, or component quality issues. Surprisingly, many failures originate from a much simpler source: selecting the wrong sensing switch. A common example occurs in consumer electronics and industrial equipment where designers use a micro … Read more

If you’re specifying a USB connector for a new product, you’ve probably run into three overlapping terms: USB-C, USB 3.0, and USB4. They sound like a version progression, but they actually answer three different questions — connector shape, data speed, and protocol capability. Choosing wrong can mean redesigning your PCB six months into production. This … Read more
