"PB spring" can refer to a spring made of phosphor bronze (PB) or, in some contexts, a spring with a specific function or type like a push-button spring ("PB Spring Rtn"). In mechanical engineering, PB springs are compression springs designed for specific applications. They are made of phosphor bronze and are commonly used in various industries due to their corrosion resistance and non-magnetic properties. In electrical contexts, "PB Spring Rtn" might refer to a spring-return push button, often used in electrical panels or control systems.
