A Tactile Switches is a momentary-contact electronic component that rapidly closes or opens a circuit when minimal operating force (typically 1-5N) is applied. Upon pressure release, its internal metal dome automatically resets to break the connection13. Core characteristics include: Key Structural Components: plaintextCopy CodeTerminal Pins → Electrical contacts Base → Structural support Metal Dome → Conductive element (copper/silver alloy) Button → Transmits external force Cover → Dust/contaminant shield The comparison between tactile switches and push button switches, maintaining technical accuracy and structural clarity: I. Core Operational Principles II. Structural & Performance Comparison
USB-C Connector is gradually replacing USB-A, and product selection needs to pay attention to these In the past decade, many connectors in the field of consumer electronics have been replaced by USB-C Connectors in the integration. But how difficult is it for USB-C Female Connector to be “universal” for terminals? The 3.5mm audio interface gradually disappeared from mobile phones, and the Lightning interface on the iPhone and the Micro-USB interface on domestic mobile phones were gradually replaced by USB-C. For terminals, can USB-C connectors really meet the requirements of “universal
DC power sockets are designed for direct current (DC) electrical connections, widely used in electronics, automotive systems, and industrial equipment. Key details include: Basic Structure and Features Interface Types ◦ Barrel Jack: Most common (e.g., 3.5mm/5.5mm outer diameter for routers, cameras).◦ Aviation Connectors: Industrial-grade waterproof design with screw locking (e.g., GX16-3 pin).◦ USB Type-C: Supports bidirectional power delivery and fast charging (PD/QC). ◦ Cigarette Lighter Sockets: For 12V/24V automotive power. Core Parameters ◦ Voltage: 5V, 9V, 12V, 24V (must match device requirements).◦ Current: 0.5A–10A+ (high-current models require enhanced heat dissipation).
