標題 "Enclosure & Push button box (英文版)" 在電氣行業中指的是兩種不同的設備： 1. **Enclosure (外殼):** An enclosure, in the electrical context, is a protective housing or case that surrounds and shelters electronic components, wiring, or machinery from environmental factors such as dust, moisture, and physical damage. Enclosures can come in various forms like cabinets, NEMA-rated boxes, junction boxes, panelboards, or even outdoor-rated enclosures for use in harsh or exposed environments. They are designed to meet specific industry standards for protection levels (e.g., IP ratings). 2. **Push button box (按鈕箱):** A push button box, also known as a switch box or a control panel, is an assembly containing one or more electrical push buttons used to initiate, interrupt, or change the state of a process or device. It usually consists of switches with different functions, like normally open (NO) and normally closed (NC) contacts, along with other controls like indicator lights, fuses, relays, and possibly input/output terminals for connecting to external devices. These boxes are commonly found in industrial, commercial, and residential applications for controlling access, signaling, and initiating mechanical or electronic operations. In summary, the user is likely seeking information on the selection, specification, or installation of both an electrical enclosure to protect sensitive equipment and a push button box for managing manual control inputs within a given electrical system.
